Reply:I guess you need to know about computing concepts first. With C its almost possible to build any software and program you can imagine under the sun, not just the operating systems.
Reply:ooo.. u r one inquisitive soul..


1. Yes there are OS's made in C.. ever heard of UNIX?


2. Its ur will whether to write a program for addition of numbers or not.


3. U can not make OS's using other C programs.. the OS is a program in itself.. well to answer wisely.. u need to learn a bit more about computers first before u start out in the project..


4. U can make a C program using a C editor.. then bundle it up wid the libraries and make it into an exe.. then u r done
Reply:1. Yes! C can be used to write OSes but it is no easy task. Also so part of the OS will usually be written in Assembly Language but the bulk of it is in C. Eg: Linux.


2. An OS is like the foundation of a building. You must have it... what you build on top of it is upto you. Thus the "task" or "duty" of the OS is to provide a suitable platform which can be used to run other programs. Those programs may be as simple as ones for adding two numbers to as complex as a Word Processor or an Action game.





The programs that your write to print messages and add numbers are meant to help you understand concepts and syntax. These programs help you grasp the meaning of printf and scanf so that you are in a position to use these in more complex practical programs.





3. Writing an OS is not an easy job. A large team of expert progammers usually take months or even years to develop a good working OS. For details refer to "Operating System Design %26amp; Impliemntation" by Tanenbaum.
