Newest Programming Challenge

i found the lack of basic programming skills in prog
disturbing, so today and for the next 52 weeks
i m gonna try teach people on prog and maybe /g/ how to program
through small programming challenges.
CHALLENGE NUMBER I
1.copy the following  lines to a small text editor
2.save it as hello_world.c
3.open up a termnial
4. give gcc hello_world.c -o hello_world -Wall
5.type ./hello_world to execute it
VOILA!! you've just finished the first challenge
one step closer to being a programmer

//VODE
#include <stdio.h>

void main()
{
   system("echo hello world!");
}
//CODE
