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?

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.

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.

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

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?

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?

I want to write a program in C language (in graphics mode).

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?

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

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?

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!?

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;

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 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, ...)

Suppose the input is "15"


And the output is "F"





Please let me know how it work and how is the algorithm. I try to make it for 3 days but i confuse. I have a problem with how we save tomporaty the number and the counter to count how many digit is the output.

Thanks for ur help.


Good luck. Have a nice weekend..

Anyone can help me to make a "C language" program?
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 */








If you're doing this for a class, then the instructor might have told


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;


}

use something like

These will invoke the native OS calls to do what you want. Its also really ugly. I am hoping someone else gives you a better way to solve this problem!

If you want to print variables and string using printf.. you will need to do:


printf("\nName:%s\nFrom:%s\n", str1, str2);





Output: (str1 = John, str2 = Yo)


Name: John

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

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?

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?

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:yes i tcan be done........... but i donno how to do that...........
