Why void main shouldn't be used instead of int main?

Question

Function

Answer 1

In C standard, any return type is valid on compiling, but throws Non-zero code exit for return type other than int and leading unproper close of the program and memory junks.

To avoid these problems occuring in C on runtime, when C introduced with classes as C++, C++ standard made strict implementation of int return type for main function... return 0 in main function means the proper closing of the program and cleaning of memory junks...

Read all the comments embedded inside the following codes...

I also attached usage case of return 0 in main both C and C++
