Wink you mean C Program?

Do you mean that you want to write a C Program on linux and run it?
Do this:
#yum install gcc*
or
#rpm -ivh gcc*

open vi editor and type the program.
#vi sample.c (file extention should be .c)
#include<stdio.h>
main(void)
{
printf("Welcome to the world of C");
}
---save the file (:wq)
#gcc sample.c
--it produces a file called a.out
#./a.out

Welcome to the world of C
(which is your out put)

As I understand it, all functions in the standard C library are in the GNU libc library. Source code can be downloaded from http://www.gnu.org/software/libc/.
