Write a C Program without Main()...!!

well all of you must be thinking i m crazy... well here is a stuff which will blow up your mind... Everyone used to study that main() is the starting point of any program... well have a look at this code... if you don't believe me then try it out yourself... the program does not have a main anywhere in the program... still it will compile and show the output screen....

#include
#include
#define rohit(s,h,o,c,k,e,d) c##s##o##h
#define happy rohit(a,n,i,m,a,l,s)

int happy()
{
    printf("\n Rohit loves C programming");
    getch();
    return 0;
}

Here's a screen shot of the program... enjoy....
