The basic steps for compiling a C program using GCC are as follows (for example, "Hello,world" program):

1. Edit source program [email protected]: ~/clang$ gedit hello.c

#include <stdio.h>

int main (void)

{

printf ("hello,world!\n");

return 0;

}

2. Compile the source program [email protected]: ~/clang$ gcc hello.c-o Hello

If the source program is written using the C99 standard, add the-STD=C99 option as follows:[email protected]: ~/clang$ gcc hello.c-o hello-std=c993.

Run executable [email protected]: ~/clang$ ./hello
