Hi

How can we run a " C Langauge program without writing the main function

It is possible to do it. but can anyone explain this with an example?

When a C program is executed the main() is the function called by the run-time environment. But it is possible to write C program without main() function with some trick. I have not done this but will make a try and let you know. Nice question posted which triggered me to try this out.

#include<stdio.h>
#define decode(s,t,u,m,p,e,d) m##s##u##t
#define begin decode(a,n,i,m,a,t,e)

int begin()
{
printf(" hello ");
}

I disagree - clever though.

That's still has a main function. If you trace through what the #define's are doing it's just changing "begin()" to "main()". The compiler still sees and compiles "main()".

It sounded like Dharmesh rathod wanted no main function whatsoever rather than obfuscated code.

a program must have a main function (compulsory) without main it is impossible

As I know its not possible to run a program without the main function.
