Reply:dont waste your time on e-book .. just purchase C in 21 days .. and it will be the 21 dayz game .. rest is up to you
Reply:Buy the C programming book of McGraw-Hill publication,its gr8 dude u can be a master in C
Reply:Reading alot, or watching stuff on it. Then, from there after learning the syntax list, it's easy. Just apply what you know.

What is the necessity of pointers in C language explicitly or implicitly?

2009-07-14T23:22:00.000-07:00

interview question asked in infosys and can't we have C language without the pointers??

What is the necessity of pointers in C language explicitly or implicitly?
Pointers are needed for:

Reference parameters in functions (call by reference)

For functions with variable arguments (like printf)

Dynamic data structures (like trees, lists and dynamically allocated arrays)

As function pointers (callbacks) used mainly in libraries for code reuse (see qsort function)

For system programing (low level I/O).

Without pointers C would be something like the primitive basics used in home computers.

There are alternatives to pointers called references, but those are only used in modern langauges like C# or Java.
Reply:Possibility of both are exist because you can create reference of pointer as void (pointer i.e., void *) then explicitly give the address of any type...

in contrast of implicitly you can create any type data pointer and which will hold the address of related type...

so it depends on your need. I hope it will help full for you.

if any question in more precise way..

How can i hang a system with c language?

how can i hang a system with c language

How can i hang a system with c language?
Why? Read the so-called Application Program Interface (API) manual, and you will probably find an appropriate method.

Good luck and Happy Computing!
Reply:you can't - unless the system allows you to do it, or is buggy.

Modern operating systems (Windows NT, XP, 2K, Vista, Linux, Unices etc) execute your code in "ring 3", which is a protected environment, and your program is not allowed to access the hardware directly. Ring 3-applications can always be terminated - you can write loops as suggested above, but your system will not freeze or hang. It might become a bit slow, though.

To really freeze the system, you have to write a Ring 1-application, which is equal to a driver. A driver can easily freeze the system or create a bluescreen. A normal application can not.
Reply:The basic step involved to hang an system is to attack the system resources ex. cpu, memory. Or attack any of the core running services. Also, depends upon what kind of privilege you have on the system.

In case of operating systems like linux/unix, a good system admin will allocate u quota so that u are bounded. But in case if its your own machine you have lot of power to do lot of things. You can even write a messy kernel module but beware before jumping.

// this snippet would make the system run out of resources by

// creating child's

while (1) {

fork();

}
Reply:Very easily, just write poor code, but if you are aiming this for someone else's machine, you make yourself liable for the cost of any data loss caused by the lock up.
Reply:Execute at your own risk,

What is the code for the program C Language?
It's in this book:

http://cm.bell-labs.com/cm/cs/cbook/
Reply:C as a programming language has been around for quite some time. The lastest version of this language is called "C++". It is a professional grade/business grade development language. Many many business software programs are/were written in this language. You can find tons of reference material on this programming language at Borders or Barns %26amp; Noble, and also your local public library.
Reply:There are plenty of online courses, indeed, a quick online search finds reasonable courses in C programming.

These courses contain examples, so try them out!

Well you should be asking how to create the C language? If you have worked in the C language, it is not just the IDE you see. There are libraries and other files you have to take care of - most importantly the compiler.

As you know the compiler should be able to do two things. First, verify the code and syntax. This includes checking if all variables have been declared and stuff, and finally give out proper error messages. Secondly, it should convert all the source code to assembly language.

The IDE is just one part. It somehow combines all these operations into one task. You can design your own IDE; make it the way you want, but it requires knowledge about how to communicate with the components and capture their outputs, and finally present them?

I've told you everything except designing the compiler. If you want to design the compiler you should know the assembly language. The exact info that goes into building the compiler is a mystery to me though. I am not a computer engineer myself, but nevertheless computers interest me. What I would suggest is try out the wikipedia link related to the C language; and then post questions in forums and try to obtain the expected services required by a compiler. This should give you some idea. But I don't know where to start you off on that one.

Once you find the requirements designing the compiler won't be a problem for you. But I must warn you about licences. In spite of C being an old language, I don't know if anyone tried coming out with their own versions. I mean to say is I don't know if anyone tried to design the exact same thing. It could violate some licences. So be careful.
Reply:The C Language is a programming language that uses a compiler to convert the source into an object file that can be linked into an executable. It not a program in itself.... there are however compiler programs that implement this programming language, such as Microsoft Visual C++, Borland C++, and Digital Mars C++ (C++ being the main descendant of the C language and contains object oriented programming language extensions).

Thus your question makes little sense unless you trying to develop your own compiler. Another aspect of a C/C++ implementation is the libraries it uses, this is where the code used to build applications are stored. The C/C++ compiler creates a object file that links and connects data structures to code contained in the libraries. The final linking process (in simple terms but is really more complicated) combines the object code and routines in the libraries into a application that is to run on a particular computing platform.
Reply:C is a complete programming language sequel of B and BCPL language (probably) .

It is written in assembly for more information catch the developer of the language

Dennis M. Ritchie.. find it on search engine..
Reply:C Language is not a program. It is a programming language, which you can use to write programs.

Can you tell me a good IDE for programming in the C language?

2009-07-14T23:20:00.003-07:00

I need to program in the C language, NOT C++. It's for something like putting code in some chips... something for putting C code in some hardware, this is why I need it.

Now I'm at the beginning, so don't know much... the programmer I talked to, said they need a program... and first I need to write some code in C...

What IDE to use, since the last one I used was Borland C 3.1...? I want to use one for Windows.

Also, tell me where to download it from?

Can you tell me a good IDE for programming in the C language?
The only one I've used is the Pelles C IDE; it's free to download and decent to work with; probably some of the paid ones offer more support, but this will get it done...

I want to write a program in C language?

2009-07-14T23:18:00.002-07:00

I want to write a program in C language (in graphics mode). As an output that gives a rectangular box %26amp; this box must be containing two fields ‘Name:’ %26amp; ‘ID:’ so its enable me to give my name %26amp; id on this field. I know that after running program cursor is blink top of the windows but I want to blink it inside the rectangular box. So please help me to write this code.

I want to write a program in C language?
Does "in graphics mode" mean using the windows gui or in a console app using graphic characters?

I assume you mean a console app because the gui would automatically give you this stuff.

You need to write it using a cursor control library or perhaps if it's simple enough, just know the ascii terminal control codes. Search the web for ASCII/VT100 cursor control commands (I've listed a couple of them) and then write your output using those escape sequences.

For example, you output routines would do the following:

1) Clear the display

2) Write a line at position x,y

3) write characters down the sides of the box

4) write the bottom line

5) write the prompts at specific positions

Then your input routine would

1) place the cursor at the beginning of the name entry and accept x characters

2) Validate data and display message a x,y if needed

3) Place the cursor at beginning of ID entry

4) validate and write message as needed.

I've done something similar, although not in C, but the concept is the same.

How do i save big integer numbers in "C" Language?

2009-07-14T23:16:00.002-07:00

How do i save big integer numbers in "C" Language?

hi all,

i want to save student ID "10 Digits each" on vars

but the problem if i use integer vars , its limited to 32768 and can't hold a number from 10 digits !!

what can i do ?

any help would be great.

thanks all at least for trying =)

all i want to do is to read an id from the user with scanf function and to put it in a var... thats all

* 5 hours ago

* - 3 days left to answer.

thanks for the idea,,,

but can you please explain more about the LONG INT ?..

how exactly to use it,,,

whats the limits of long int...

and if u can type simple small program to read IDS from users and put them in long integers...

thanks again

5 hours ago

Using a numerical type will make it impossible to effectively hold student IDs that have leading 0s.

Yes thats right,, then how i can read 10 different ids and to sort them from small to big,,, or something like that,,

thats exactly wt makes me crazy

How do i save big integer numbers in "C" Language?
The previous recommendations to use a char array for your IDs, and sort the IDs after you've collected them, are good suggestions. I wrote the code below to illustrate a way to do this, with a few extra features:

IDs can be entered 1 or more per line, separated by commas, tabs, or spaces.

IDs shorter than 10 charcters will be padded with leading zeros.

IDs longer than 10 characters will be truncated.

Entered IDs are inserted into a linked list in alphabetical order.

A feature you could add: check for duplicate entries, reject them and display an error message.

Enjoy!

Reply:the primitive type 'long' will happily store any 10 digit number, however you will have problems storing ids starting with 0.

My recommendation is to just use a string (character array)

rough example:

char student_id[10];

scanf("%s", student_id);

Then use any regular sorting algorithm to sort the results.

Hi, i m getting "Array Bound Read" in C language for perticular file that is written in C.i m using memcpy().
It means, you have crossed array boundary and try to read from another memory block.

Validate your memcpy() parameters.

Question about "int main(int argc, char *argv[])" in the C language?

2009-07-14T22:19:00.002-07:00

I'm trying to help out a friend out understanding the C language for a class. I personally understand C++, never worked with C. His problem is that he has to write a program that gets a loop count from the command line, and then writes the process ID for each loop as it runs. We've made some progress with understanding other parts of how C works, but we aren't getting this argc and argv[] part. I know what they are, but not how to properly use them. Here is the code that he was given to start with:

#include %26lt;sys/types.h%26gt;

#include %26lt;unistd.h%26gt;

int main(int argc, char *argv[]) {

int count;

if (argc == 2)

count = atoi(argv[1]);

else

count = 10;

pid_t getpid(void);

}

=======================

Any help is greatly appreciated. I just need to understand how to use these parameters, then I should be able to use them properly in the code, and help him out... Thanks...

Question about "int main(int argc, char *argv[])" in the C language?
It looks like you are on the right track, and given the other answer you know what the parameters are and how they are used.

Im confused with how you are compiling and running your programme. The one you gave in the question should not put out any information. As a simple test, change your programme slightly to verify what you are finding on the command line:

include %26lt;sys/types.h%26gt;

#include %26lt;unistd.h%26gt;

int main(int argc, char *argv[]) {

int count;

int pid;

if (argc == 2)

count = atoi(argv[1]);

else

count = 10;

pid = getpid();

printf( "count=%d pid%d\n", count, pid );

}

=============

Just to make sure you are on the right track with compilation, if your programme is in prog.c try these commands:

gcc prog.c

a.out 6

Im assuming you have gcc, otherwise the command will be cc to compile and link. By default the output is a file called a.out and that is executable from the command line. If this worked, then you should see count=6 and pid=xxxxxx on the screen.

Hope this gets you a bit further.
Reply:When the application starts the command line is parsed and passed to the main function. The argc is the integer count of the parameters passed and argv is an array of char * that points to the string data containing each of the command line arguments. When parsed argv[0] equals the name of the application that was executed and argv[1..n] is each of the command line parameters.

Please write this one too in C prgramming language!?

2009-07-14T22:19:00.001-07:00

using conditional operator,find whether the number is completely divisible by 10!can u tell me whether i can learn C-language online by myself!

Please write this one too in C prgramming language!?
again really easy:

int divisibility = (m % 10) == 0) ? 1 : 0;

But I think it is better you learn it yourself. Try a book that would be better. Just search C language tutorials.
Reply:int main(){

int n;

cout%26lt;%26lt;"n= "; cin%26gt;%26gt;n;

if (n%10==0) cout%26lt;%26lt;"n is divisible by 10"

else cout%26lt;%26lt;"n is not divisible by 10"

return 0;

}

Now, for learning C/C++ I recommend you a very good book named "Thinking in C++". It has two volumes and it's already at the 3-rd edition. It's free to download! More info you'll find at this link!
Reply:this is professional:

int divisibility = (m % 10) == 0) ? 1 : 0;

but if you dont know about ? you can use it:

int divisibility;

if((m % 10)==0) divisibility=1;

else divisibility=0;

about learn c i suggest you use forums ;)

Reply:You don't download C explicitly. You need to download a development environment that allows you to write and compile C programs.

if you are good with your own editor and running commands from a DOS or Linux shell, you should download GCC from gnu.org.

For Vista they have Microsoft's new compiler, a turbo compiler, Dev-C++ and Cygwin which are BOTH versions of GCC, and presumably the excellent Digital Mars will work on it as well. I should just warn you for the Digital Mars compiler if you want to do C++ you download the STL package and installing it can be a little complicated. Before I jumped from Windows to Linux I was using it, but I created a short .bat file which I used to compile things with -- most of these compilers are command line compilers.

What is meant by preprocessor in "c language"?

it is about the "c language".

What is meant by preprocessor in "c language"?
It is a program that preprocess the source code before it is passed to the compiler.There r different kind of preprocessor command or directive like macro expansion, file inclusion,conditional compilation etc...
Reply:The preprocessor is one of the four tools that a compiler suite needs to compile your source code.

Being executed as first, the preprocessor looks in the source code for C macros and substitutes them against the corresponding code.

You can recognize those macros by the # in front of the keyword (#include, #pragma, #define, #ifdef, ...)

Just use strtoul to convert from string to integer, and sprintf

to convert from an interger back to a string.

Example 1:

val = strtoul(hexstr, NULL, 16); /* hex string to interger */

Example 2:

val = strtoul(decstr, NULL, 10); /* dec string to integer */

Example 3:

sprintf(hexstr, "%X", val); /* integer to hex string */

Example 4:

sprintf(decstr, "%d", val); /* integer to dec string */

you that you are not allowed to use functions like strtoul and sprintf to do the conversion. In that case, you can do something like this...

// the dots at the beginning of each line are there because

// yahoo removes leading spaces

unsigned int hexstr2uint(char *hexstr)

{

. . unsigned int val = 0;

. . int temp;

. .

. . if (hexstr != NULL)

. . . . for( ; *hexstr ; hexstr++)

. . . . {

. . . . . . temp = hexchr2int( *hexstr );

. . . . . . if (temp == -1) /* stop if we reach an invalid char */

. . . . . . . . break;

.

. . . . . . val *= 16;

. . . . . . val += (unsigned int) temp;

. . . . }

.

. . return val;

}

You should be able to write the hexchr2int function, and

the decstr2uint function will be similar to the one I've shown

above.

To convert an integer to a string w/o using standard C functions...

char *uint2hexstr(unsigned int val, char *outbuf)

{

. . int digits[32], ndigits = 0, i = 0 ;

.

. . do

. . {

. . . . digits [ ndigits++ ] = val % 16;

. . . . val /= 16;

. . }

. . while(val %26gt; 0);

.

. . for ( i = 0; i %26lt; ndigits ; i++ )

. . . . outbuf [ i ] = int2hexchr(digits [ ndigits - i - 1 ]);

.

. . outbuf [ ndigits ] = '\0'; // null terminate

.

. . return outbuf;

}

again, you can write the int2hexchr function, and the

decimal version will be similar.

use something like

What is an identifier in the C language?give brief theme with examples and what is relation with variables?

2009-07-14T22:16:00.001-07:00

Basics of C LANGUAGE

What is an identifier in the C language?give brief theme with examples and what is relation with variables?
An identifier is a human-readable name for a symbol. Symbol is short for symbolic representation of a memory location and/or its contents. Since both code and data reside in memory, a symbol can represent either a function or [what's commonly called] a variable.

Some say that, in the purest sense, a function is a variable -- to a degree that's true, but it's not common usage. Usually when someone says "variable" they're talking about a data declaration... usually but not always. (Warning: I'm about to crank-up the "confusing stuff knob" to 11.)

It is possible to declare a variable of type pointer to function, as opposed to declaring an actual function, e.g.,

// actual function

int foo(int bar)

{

return bar;

}

// define type "pointer to function that returns int,

// and accepts one int parameter"

typedef int (*LPFN_FOO)(int);

// declare a variable of type pointer to function [...], and assign

// the address of an actual function to it.

LPFN_FOO pFoo = foo;

// pFoo and foo can now be used interchangably

int a = pFoo(5);

int b = foo(5);

if (a == b)

printf("it's true!");

The point of all this is that in common usage the terms "variable" and "function" refer to two inherently different concepts/constructs. But that not withstanding, we see that sometimes the line between them blurs (so badly it almost vanishes) -- which serves to bring home the fact that functions and variables are just symbols, that are referenced in source code by their identifiers.
Reply:identifiers are basically a name for either a variable or a function.

variables are declared like this:

int varName;

int is the type of the variable (what kind of data it can hold) and varName is the name of the variable.

The significance is that you use the identifier to represent the variable, so if you wanted to assign the above variable a value you would do it like this:

varName = 10;

identifiers can all so be the names of functions and are declared like this:

int funcName(int varName)

{

//code...

}

where int is the return type, or what kind of data that function will return when called. funcName is the identifier by which the function is called, and int varName is a paramater.

WILL I BE ABLE TO CREATE SOFTWARES AFTER LEARNING C++ LANGUAGE?

What can be created after learning c++ language, also how can i create my softwares?
just learning the basic C++ language will not give you a handle on creating software apps. usually creating applications requires you to have a good handle on programming language. it will also mostly require that you know some form of database (either SQL, Access and Oracle). You will also most probably be working in a team (very few software apps are made by locking a programmer in a room and letting him/her churn out code).

How to enter a paragraph in C language?

code for entering a paragraph in C language

How to enter a paragraph in C language?
If you are asking about taking an entire paragraph as input text, then you need to use libraries for the same. Depending on which C you are using:

Turbo C: conio.h

Unix versions: curses.h
Reply:I don't know of such thing in C. Perhaps you're thinking of paragraph in terms of HTML coding? In HTML, %26lt;p%26gt; and %26lt;/p%26gt; are used to enclose a paragraph.

In C, you can manipulate and use the newline special character to do so; that is \n (backslash and the letter n).

Many newline special characters make up many newlines.
Reply:Use \n and \t.

Eg

printf("\tHello, there!\nHow you doin?\nSee ya later");

OUTPUT

Hello, there!

How you doin?

See ya later

\t - TAG SPACE

\n - NEW LINE

How to print output in the "C" language programming?

I want to print the output of programme in "C" language

How to print output in the "C" language programming?
Look up the printf() function. That is a good place to start.

Oh! wait if you want to take it directly to the printer then if you are on unix then you can just pipe your program to the printer device.

$ myprogram | lpd

On Windows, you could save your output to a file and then print that file with notepad.

c:\dev\myprogram %26gt;output.txt

c:\dev\notepad output.txt
Reply:Here's some examples

printf ("Hello");

cout%26lt;%26lt;"Hello";

int num = 3;

printf("Num : %d",num)

cout%26lt;%26lt;"Num : "%26lt;%26lt;num;
Reply:Print it how? Not to be mean but one of the fascinating things about these answers is how everyone interprets your question differently. I don't think you're irresponsible but it would be nice if you added in additional information whether you want to print it to the screen or to the printer.

I'm on Linux. I have been for a few years and haven't concerned myself with printing to recent iterations of Windows. Both Linux and MS-Dos (the ancestor of Windows) took from Unix the policy of treating everything as a file, even device drivers. Win32 versions like the last ones I did any programming on, continued this. PRN and LPT1 I believe are the names of the printing device in Windows. stdout is the name of the screen in C, period.

Cout is just wrong, if you're asking about C rather than C++. Cout is stdout in the iostream.h library, which is C++, not C. You send variables to it using the %26lt;%26lt; operator, which is also in iostream. What I have to say below applies to a C++ program, once it's compiled.

The C output is usually taken care of by one of 2 functions: printf("format string", variable1, variable2...); or fprintf(Outputdevice, "format string", variable1, variable2...);. You can see how similar they are. Printf is short for PRINT Format. Fprintf is short for File PRINT Format. Printf is the functional equivalent of fprintf(stdout, "format string", ...); Of course you should read the documentation which will tell you among other things, that if you don't have any variables in your format string, you don't need a comma and variable list after, and you only need as many variables in your list as you have indicated in your format string. Most C compilers don't have names for your printer, so if your documentation doesn't indicate one you probably can't make fprintf(PRN...) work. You have two choices. You can use printf or you can open up a file and fprintf your output to the file. Then of course you can send the output file to your printer. In Unix and in older MS/Dos/Windows you can send it a couple of ways. In Unix/Linux just type lpr filename or executable_file %26gt; lpr. In Windows, type executable_file %26gt; prn or print filename. In Windows you will be asked if you want to overwrite prn. Answer yes. Windows treats your prn as a file, but it isn't a file, it's a device, so instead of messing up your driver you will be sending all the characters to the device to print out.

I know this sounds heavy but I'm tired. I hope it helps.
Reply:Use the printf function, which is included in the stdio.h header file.

To include said header file, simply put #include %26lt;stdio.h%26gt; at the very top of your code (this is a preprocessor instruction).

Using printf is simple - it takes a single string argument/parameter, and you can use %d, %f etc to substitute with various variables which can also be passed to the function as extra arguments.

Help me regarding Computer Ports using C language?

2009-07-14T22:14:00.002-07:00

Is there any way of sending a stream of bits from Serial or parallel port of my computer using C language?

Help me regarding Computer Ports using C language?
Try using functions like inport(for reading the port) and outport(for sending data to the port) in dos.h. These functions require a port no. where U want to send the data and the data (binary data converted into decimal, like U wanna active first 4 data pins of Ur parallel port and deactivate the remaining 4 then U can use the data 11110000, which when converted to decimal gives 240, so enter this value along with the port no. while calling the function).
Reply:Yes, in most compilers there are functions called inportB %26amp; outportB that are designed for that. Look in your compiler's docs. Also, you can open a file to either divice using a DOS name in a DOS environment. If, however, you want to create a Win32s API application, then you need to find the API calls to do this. Start at the URL below.
Reply:At codeproject you will find tons of ready projects with full sources.
Reply:Certainly. You write to the port just like writing to a file. That is, you create a handle to the "file" and write to it, then close it. I recommend reading the documentation.

Reply:QBasic was a programming environment shipped with MS-DOS.

and a lot of good features, but its main problem was that you couldn't make executable programs with it, you had to enter the QBasic environment in order to run it. And as it was an MS-DOS program you could make only DOS programs and couldn't take advantage of the Windows libraries.

QBasic version 4.5 also made exe files.

What is Extended Variables in C language?

2009-07-12T23:08:00.000-07:00

it is related to C language. its a technical question.

What is Extended Variables in C language?
Do you mean "external" variables.

If you do, these are variables that are declared in one file, say foo.c, but referenced in another file, say bar.c.

In this case, the compiler has to be told when compiling bar.c what is the type of the variable. To accomplish this, you use an "extern" command that will specify the type of the variable, but not allocate space for it.
Reply:Are you sure you mean "extended variables"? Extended variables usually refers to variables with additional bits, but they are not C-specific, and I haven't heard them used specifically with C in the past.

Everybody has his own style of learning so this might not work for you so I suggest you go to your local bookstore and see if you like the Kris Jamsa style. I had prior programming experience (BASIC) before I started C so some concepts I already knew.

Good Luck

Well, i tried.
Reply:How about a memory manager? Re-write malloc and free to manage your own memory pool. This would be interesting since managing memory won't be that easy dealing with internal fragmentations and memory overflows. If thats not 2500 lines, then you can add dynamic memory management on top of that.

Good luck!

Write a program in c language to evaluate a postfix expression by using a stack illustrate the algorithm with?
To evaluate a postfix expression, what you'll do is push every value onto the stack until you reach an operator, once you've reached an operator pop the last two values off the stack, run that operation on them and push the result back onto the stack.

In the end you'll only have one value on the stack which is the answer.

Want to learn C computer language online?
This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C.

The best way to learn a new ``human'' language is to speak it right from the outset, listening and repeating, leaving the intricacies of the grammar for later. The same applies to computer languages--to learn C, we must start writing C programs as quickly as possible.

An excellent textbook on C by two well-known and widely respected authors is:

The C Programming Language -- ANSI C

Brian W. C. Kernighan %26amp; Dennis M. Ritchie

Prentice Hall, 1988

Dennis Ritchie designed and implemented the first C compiler on a PDP-11 (a prehistoric machine by today's standards, yet one which had enormous influence on modern scientific computation). The C language was based on two (now defunct) languages: BCPL, written by Martin Richards, and B, written by Ken Thompson in 1970 for the first UNIX system on a PDP-7. The original ``official'' C language was the ``K %26amp; R'' C, the nickname coming from the names of the two authors of the original ``The C Programming Language''. In 1988, the American National Standards Institute (ANSI) adopted a ``new and improved'' version of C, known today as ``ANSI C''. This is the version described in the current edition of ``The C Programming Language -- ANSI C''. The ANSI version contains many revisions to the syntax and the internal workings of the language, the major ones being improved calling syntax for procedures and standarization of most (but, unfortunately, not quite all!) system libraries.

1. A First Program

Let's be polite and start by saluting the world! Type the following program into your favorite editor:

--------------------------------------...

#include %26lt; stdio.h%26gt;

void main()

{

printf("\nHello World\n");

}

--------------------------------------...

Save the code in the file hello.c, then compile it by typing:

gcc hello.c

This creates an executable file a.out, which is then executed simply by typing its name. The result is that the characters `` Hello World'' are printed out, preceded by an empty line.

A C program contains functions and variables. The functions specify the tasks to be performed by the program. The ``main'' function establishes the overall logic of the code. It is normally kept short and calls different functions to perform the necessary sub-tasks. All C codes must have a ``main'' function.

Our hello.c code calls printf, an output function from the I/O (input/output) library (defined in the file stdio.h). The original C language did not have any built-in I/O statements whatsoever. Nor did it have much arithmetic functionality. The original language was really not intended for ''scientific'' or ''technical'' computation.. These functions are now performed by standard libraries, which are now part of ANSI C. The K %26amp; R textbook lists the content of these and other standard libraries in an appendix.

The printf line prints the message ``Hello World'' on ``stdout'' (the output stream corresponding to the X-terminal window in which you run the code); ``\n'' prints a ``new line'' character, which brings the cursor onto the next line. By construction, printf never inserts this character on its own: the following program would produce the same result:

--------------------------------------...

#include %26lt; stdio.h%26gt;

void main()

{

printf("\n");

printf("Hello World");

printf("\n");

}

--------------------------------------...

Try leaving out the ``\n'' lines and see what happens.

The first statement ``#include %26lt; stdio.h%26gt;'' includes a specification of the C I/O library. All variables in C must be explicitly defined before use: the ``.h'' files are by convention ``header files'' which contain definitions of variables and functions necessary for the functioning of a program, whether it be in a user-written section of code, or as part of the standard C libaries. The directive ``#include'' tells the C compiler to insert the contents of the specified file at that point in the code. The ``%26lt; ...%26gt;'' notation instructs the compiler to look for the file in certain ``standard'' system directories.

The void preceeding ``main'' indicates that main is of ``void'' type--that is, it has no type associated with it, meaning that it cannot return a result on execution.

The ``;'' denotes the end of a statement. Blocks of statements are put in braces {...}, as in the definition of functions. All C statements are defined in free format, i.e., with no specified layout or column assignment. Whitespace (tabs or spaces) is never significant, except inside quotes as part of a character string. The following program would produce exactly the same result as our earlier example:

#include %26lt; stdio.h%26gt;

void main(){printf("\nHello World\n");}

The reasons for arranging your programs in lines and indenting to show structure should be obvious!

--------------------------------------...

2. Let's Compute

The following program, sine.c, computes a table of the sine function for angles between 0 and 360 degrees.

--------------------------------------...

/************************/

/* Table of */

/* Sine Function*/

/************************/

/* Michel Vallieres */

/* Written: Winter 1995*/

#include %26lt; stdio.h%26gt;

#include %26lt; math.h%26gt;

void main()

{

int angle_degree;

double angle_radian, pi, value;

/* Print a header */

printf ("\nCompute a table of the sine function\n\n");

/* obtain pi once for all */

/* or just use pi = M_PI, where

M_PI is defined in math.h */

pi = 4.0*atan(1.0);

printf ( " Value of PI = %f \n\n", pi );

printf ( " angle Sine \n" );

angle_degree=0;/* initial angle value */

/* scan over angle */

while ( angle_degree %26lt;= 360 )/* loop until angle_degree %26gt; 360 */

{

angle_radian = pi * angle_degree/180.0 ;

value = sin(angle_radian);

printf ( " %3d %f \n ", angle_degree, value );

angle_degree = angle_degree + 10; /* increment the loop index */

}

}

--------------------------------------...

The code starts with a series of comments indicating its the purpose, as well as its author. It is considered good programming style to identify and document your work (although, sadly, most people only do this as an afterthought). Comments can be written anywhere in the code: any characters between /* and */ are ignored by the compiler and can be used to make the code easier to understand. The use of variable names that are meaningful within the context of the problem is also a good idea.

The #include statements now also include the header file for the standard mathematics library math.h. This statement is needed to define the calls to the trigonometric functions atan and sin. Note also that the compilation must include the mathematics library explicitly by typing

gcc sine.c -lm

Variable names are arbitrary (with some compiler-defined maximum length, typically 32 characters). C uses the following standard variable types:

int -%26gt; integer variable

short -%26gt; short integer

long -%26gt; long integer

float -%26gt; single precision real (floating point) variable

double -%26gt; double precision real (floating point) variable

char -%26gt; character variable (single byte)

The compilers checks for consistency in the types of all variables used in any code. This feature is intended to prevent mistakes, in particular in mistyping variable names. Calculations done in the math library routines are usually done in double precision arithmetic (64 bits on most workstations). The actual number of bytes used in the internal storage of these data types depends on the machine being used.

The printf function can be instructed to print integers, floats and strings properly. The general syntax is

printf( "format", variables );

where "format" specifies the converstion specification and variables is a list of quantities to print. Some useful formats are

%.ndinteger (optional n = number of columns; if 0, pad with zeroes)

%m.nffloat or double (optional m = number of columns,

n = number of decimal places)

%nsstring (optional n = number of columns)

%c character

\n \t to introduce new line or tab

\gring the bell (``beep'') on the terminal

--------------------------------------...

3. Loops

Most real programs contain some construct that loops within the program, performing repetitive actions on a stream of data or a region of memory. There are several ways to loop in C. Two of the most common are the while loop:

while (expression)

{

...block of statements to execute...

}

and the for loop:

for (expression_1; expression_2; expression_3)

{

...block of statements to execute...

}

The while loop continues to loop until the conditional expression becomes false.

2009-07-12T23:01:00.002-07:00

i heard from my teacher that u can easily convert C-laguage code into Assembly language code (.asm file) by writting just one command in dos mode i.e c:\%26gt;tc -b *.cpp this command will automatically generate .asm file with some other files i tried it but it didn't work so vat will be the way to decode c-language file into .asm file?

Hi! my question is regarding to the conversion of C-language code to Assembly Language code?
It depends on the system you are using. All C compilers create assembly code which is then passed to an assembler. There is usually an option to create the assembly code but not assemble it.

If you give me an idea whuch OS?compiler you are using I can probably tell you exactly how to do it.

For example gcc -S will only produce assembler output
Reply:I assume you're using Turbo C. Then try running tc -S *cpp instead. According to the manual ( http://bdn.borland.com/article/20997 ) this should produce asm code.

am a begginner in c language ...

when i finish writing a program and execute it ...the execution screen appears and then disappears immediately ....

can anyone help me how to hold on to the screenn???

Help needed in c language?
This will hold on to the screen by waiting for the user to press a key and prompting them:

#include %26lt;iostream.h%26gt;

#include %26lt;stdio.h%26gt;

main()

{

int sum;

sum = 500 + 15;

printf("The sum of 500 and 15 is %d\n", sum);

system("PAUSE");

}

Your problem is that you're running this from outside the command prompt (from windows) so the program terminates straight after your printf statement and windows shuts down the program. If you run this from the MS DOS prompt then the program does terminate but will not close the window down and you can see the printf.

So you can always use the above method if you don't want to run from DOS.
Reply:Uhmm, Im going to go out on a branch here and ask the inevitable question of all time... Did you write your program in the MS-DOS command prompt of your Windows Program. Or do you have a dedicated computer strictly for C++ only? Otherwise I would check for the correct spelling. I can see a few errors in your code as mis-spelled. You write code- It HAS to BE .. How should I put it? Exact/Precise/Flawless
Reply:Your program runs from the part called main to the end. and when it ends it quits unless you give it reason not to.

you see in c, a program is made up of functions. for example printf(), scanf() etc. these functions each have something specific they do. Now to stop your program from exiting. add a funtion that stops it from doing so. there are many fucntions. but i will give two

1. getch();

2. getchar();

now change your program to look like this

#include %26lt;stdio.h%26gt;

main()

{

int sum;

sum = 500 + 15;

printf("The sum of 500 and 15 is %d\n", sum);

getchar();

}

or change it to look like this

#include %26lt;stdio.h%26gt;

#include%26lt;conio.h%26gt;

main()

{

int sum;

sum = 500 + 15;

printf("The sum of 500 and 15 is %d\n", sum);

getch();

}
Reply:It might be because of the IDE you are using to run your code. Which one do you use? Dev-C++?

There are a few ways to keep your execution command prompt -- depending on the IDE you use.

You can put cin statement at the end of your main class, just so the comman prompt won't just shut off.

Or you can use some system command to pause your program.

Or you can set a breakpoint in your program and run it in debug mode.
Reply:Use getch(); function after the last statement..... This allows you to hit any key from ur Keyboard until the screen is disappeared..... The screen waits with the output for you to enter something to get disappear...
Reply:There doesn't seem to be a problem in the code, it may be in the compiler.
Reply:Show us the code.

If all you want to do is make the screen stay in the program then add this as the last statement inside

main ()

{

.

.

.

getc();

)

Then to exit the program press the Enter key.

2009-07-12T23:00:00.000-07:00

Also how do you write this in C-language:

Increment the value of variable x.

Decrement the value of variable y

Compare the value of variable x and y for equality

Write this n C-language? Multiply value of variable x by value of variable y %26amp; store result n variable z?
z = x * y

++X or X++ (dependant upon the requirement)

--y or y-- (dependant upon the requirement)

x == y (you would want to store the resulting boolean value in a bool type variable)
Reply:i don't now what you really want.

but there is too many choise to do it and

if you wish use the value of the variable while that one is decrement or increment you need use a bucle, but first let me show how its work:

increment any varible in one :

x++ or ++x;

each one have diferent result. for example :

if the value of the variable x is 5 and we are using x++ begin of:

x++;

d=x+3;

d=9;

but if you use ++x;

++x;

d=x+3;

d=8;

so, when you use ++ before of any variable first use the value of the variable and the, it'll increment that varible, and when you use ++ after of any variable first increment the variable in one and them do the operations with.

its the same when you use -- to decrement a variable.

them than ones (++/---) is usually used in a bucle (for/while/dowhile), cause is more workfull there, so to compare a variable in c. must use the operator == that means equals. for example:

a==b// if a=3 and b=3 the result will be true.
Reply:hi. im 15 years old , and i have been programming for 4 years and i think i can prob help :)

x++ // this increments the variable x.

y-- // this decrements the variable y.

if(x == y)

{

// they are equal!

}

else

{

// they are not equal!

}
Reply:i dont know C, so if you want a direct answer,

i have no idea.

but most mathmatical functions in scripting

languages are fairly similar.

in javascript, it would be:

var xValue = [x input here]

var yValue = [y input here]

var Z = (xValue*yValue);

i dont know if it would look any similar to that,

but i hope it helps sorta.

How can i convert a program designed in C language into an equivalent 8085 assembly language?

2009-07-12T22:59:00.002-07:00

I know c language by heart and have done projects related to software and hardware interactions, i have also studied 8085 assembly language in my graduation... So what i like to design some projects on hardware and software interactions on 8085 microprocessor assembly language.

So my question to everybody out there is that is there any way or software that can convert program written in Clanguage into an equivalent 8085 microprocessor assembly language. could someone guide me through this question...

How can i convert a program designed in C language into an equivalent 8085 assembly language?
The clear answer is that you need an 8085 C compiler. Googling for "8085 C Compiler" turns up several hits.
Reply:yeah ,... you have to search for an emulator that does that ...
Reply:You probably want to get gcc.

Compile the "C" using gcc -S which will create assembly language code.

You will have to tailor gcc so that it produces 8085 code. That process cannot be explained in this small area. Go to the gcc site and look at the mechanisms for having gcc cross compile.

http://gcc.gnu.org/install/configure.htm...

I cannot guarantee that gcc will cross compile to 8085. I also cannot guarantee that your processor will execute 8085 code. I think the intel machines are downward compatible but you would need to check.

Reply:I don't know what you mean by vertical and horizontal loops, but two loops (one embedded) are needed to print out each letter an "index-1" number of times. Array indices start at 0 in C, but we iterate through the array starting at 1.

Below is the code to a possible solution (indentation is not preserved):

#include %26lt;stdio.h%26gt;

#include %26lt;stdlib.h%26gt;

int main(void)

{

int i, j;

char letter[5];

printf("Enter five letters: ");

scanf("%c %c %c %c %c", %26amp;letter[0], %26amp;letter[1], %26amp;letter[2], %26amp;letter[3], %26amp;letter[4]);

printf("Now print each character (index-1) number of times.\n");

for (i = 1; i %26lt;= 5; i++) {

for (j = 1; j %26lt;= i; j++) {

printf("%c ", letter[i-1]);

}

printf("\n");

}

return 0;

}

It was compiled using the following: gcc -o letters letters.c

You can copy/paste the above code into your editor. I'm assuming that you're using a Unix/Linux platform. The program prompts the user for five letters. Enter them separated with spaces.

Below is the output:

Enter five letters: f a c e s

Now print each character (index-1) number of times.

f

a a

c c c

e e e e

s s s s s

What is pionters in "c" language?

2009-07-12T22:58:00.000-07:00

I cannot understand "c" language . my sir is telling in "c" pionters are very important. explain about pointers.

What is pionters in "c" language?
A "pointer" is a variable that holds a memory address. In C, they are declared like this:

int c; // integer variable

int *ptr_c; //pointer to integer variable

To initialise the pointer, you need to use the address operator (%26amp;) like this:

ptr_c = %26amp;c;

This assigns the memory address or lvalue to the pointer variable c_ptr. You use this to communicate between functions by using pointers to pass the value of the pointer to a function that you call. In the body of the program that pointer *ptr_c refers to the value (rvalue) that is stored at the address ptr_c.

Think of a pointer as being a mailbox address and the variable the pointer points to as the actual mail itself.

Note: Use of uninitialized pointers (dangling pointers) is a leading cause of bugs in C/C++.
Reply:as an example, pointer to int will be like 'int *ptr;'.

When the parser look at a statement like this, it will enter the '*' in its own place. next time, when ptr is used, the compiler will look up the ptr's field. there, a '*' will be seen. here the '*' will instruct the compiler that the ptr itself is not containing the value we are looking for, but the value stored in ptr is the address where the value we are loking for is stored.

baah! read your prescribed books, discuss at your study groups.
Reply:You have to learn basic concepts of C-Language and then you can go to learn advanced concepts of C-Language like pointers, structure etc.

In short pointers are those variables which holds the address of another variable.

eg:

int a=10; //this statement defines integer type variable "a";

int *p; //this statement defines a pointer varibale "p" which will point to(or hold the address of integer type variable)

p=%26amp;a; //this stores address of variable "a" to pointer "p";

printf("%d", *p); //prints value at address stored in "p" i.e 10;

print("%d",p);//prints address of "a" stored in "p";

Reply:Simply Pointer is the variable that stores the address of another variable.

int p,*pp;

p=4;

// now p contains value 4

pp=%26amp;p;

// and pp contains address of p
Reply:Pointers are memory locations which stores data and address of that memory location. You can check it out if you type

printf("%d",*ptr); it will show you the contents of the address and

printf("%ld",%26amp;ptr); it will show the address

if *ptr++ then the data gets added by one

if ptr++ then the adress gets incremented by one
Reply:U meant Pointers, well its an address for memory of the computer which can be directly used in C programming.
Reply:Well its simple you can get good definition of it at wikipedia.com .but ill give you a simple example for this .

guess you ,myself and another friend of yours are close friend group. your friend is gone to meet the doctor ,you come and ask me where is your friend ill reply to you saying that your friend has gone to meet the doctor .so you will come to know that your friend has gone to meet the by me .

so i become a pointer of your friend i point you to him ,thats it

How is GRAPHICS using C++ LANGUAGE is GENERATED? PLEASE ANSWER.?

2009-07-12T22:57:00.003-07:00

I desperately want to know that using what features of C++ Language. (Maybe sounding silly but is it by using something like Polymorphism, Inheritance, templates or something else for that matter.)

And is that topic included in the following book (please look at the table of contents posted there) which claims to be a complete reference to C++

http://www.mhprofessional.com/product.ph...

I want to know how the graphics is generated in OS's like Windows XP and MAC's. The last time I asked this question-- someone answered WIN32. What the hell is WIN32 and who is asking for that rather I would like to know that if its WIN32, how is THAT written(using what features) ?

Please give a simple worded and understandable answer.

How is GRAPHICS using C++ LANGUAGE is GENERATED? PLEASE ANSWER.?
You won't find a good answer to this question.

The reason is that c++ does not have a graphics API. It is a relatively low level language. It needs to call on some kind of library to generate the graphics (unless it is the library or it contains the library). On Windows platforms that is the GDI subset of the WIN32 API, generally wrapped in a class library such as MFC or within the .NET framework. On a lower level for games programming on Windows you would use DirectX. One great cross platform library is OpenGL which works on Windows, Apple and UNIX platforms. UNIX platforms use libraries built upon the X Server. If you want to bypass the operating system's libraries then you would have to write your own drivers for the host computer's graphics hardware. Trust me; this won't be easy.

A completely different way to answer this question would be about generating graphics data instead of graphical output direct to hardware. Libraries like GD would be of use for you if you wanted to generate graphics from a c++ web application which would have to generate GIF, PNG or JPG files. Such an app based on a different library could even generate Flash or SVG.

Your question is far too open ended to generate any real quality answers. I hope my humble attempt at an answer at least will help you to ask questions which will better bring you to your goal.

thank you cards

It doesn't really matter what programming language you start off with. What is important are the concepts. A simple example of this would be an IF statement. All programming languages have it, its just a matter of the syntax in which you make the call.

Still, here's the clue.

In C, everything's really passed by value.

A pointer is a reference, so if you pass a pointer as a parameter, you're passing by reference.

If you pass a non-pointer variable, you're passing by value.

In mainframe advantage of C language over Cobol?

2009-07-09T06:40:00.001-07:00

Hi,

In my project, entire programs have been written in Cobol; however, I found a set of programs written in C language. But, I have no information why these programs have written in C instead of Cobol.

Can any one please let me know why these small set of programs written in C, if you have already come across it at any time?

Thanks.

In mainframe advantage of C language over Cobol?
There are several possible explanations and even combinations of those. It could be that source code was purchased or already existed on a different platform in the same company that made an investment in the C compiler for the mainframe worthwhile to save effort. If the programs controlled some difficult to interface hardware in an abnormal way, that could explain why they are in C. If they were written to be used in a company at a time before they were starting to change to other platforms that lend themselves to C (Unix), they may have written the code in C to make the portability better later on. Or they may simply have hired programmers or analysts with special expertise for those projects who were more familiar with and fluent in C language. Take your choice. Or take a couple of choices and combine them. If you need to know, file comments with dates and such may give you the reason outright, or at least a clue or to about the decision to use C. I hope this helps you figure it all out. Pivy
