homework problem??? If so, then study about function pointers (or pointers to functions). Once you understand that then you will have the answer to your question.

The main() function is not allowed to be called inside a program. As far as I know, this means no function pointer is allowed to point to it either. I'm sure your results may vary from compiler to compiler. The only sure way is to try it yourself.

You're thinking of C++. It's legal in C (though rarely a good idea).
