void main OR int main

Question

What is the difference between these two?

Answer 1

This question is asked more than twice a day on this forum and has been post lot of time this week.

By the way, on the website of the author of c++ it's said in the FAQ that void main is not c++. So the best is to avoid it, even if some compilers allow that, it is not standard...
A program should return 0 when everything gas been done with success and an other int value to refer an error code when something got wrong.

Answer 2

here void and int are return type... they return value as null and in integer form respectively. but in void case there is no need to return type.
