Here's a C programming challenge: Can you write a C program without main()? If yes, post your code below and I will take a look.

Can you write a C program without main() ??

We had a similar thread for JAVA.

It is quite possible to write a C program without main() if we know how to use preprocessor and macro.

Yes it is possible using macros.I wanted it to be a kind of quiz 😛 Sorry may be I posted in wrong section 😔

This is the right section. 👍
Let us keep this open for responses.

This is actually the solution. Yes, we can write a program without main logically but it is not possible conceptually..
Here is the program:

#include
#include
#define decode(a,u,d,i,b,l,e) i##a##d##u
#define START decode(a,n,i,m,a,t,e)
void START()
{
clrscr();
printf("Hey this is Nick waving hi from a program without main");
getch();
}
