This may have been covered, if so, apologies, but is anyone able to give a full explanation on why the main() function of any C++ program is always of type int? C# main functions are of type void() and work just the same.
Thanks 
In C# you also can have int main() and return the exit code of the process, and void main() means exit code is 0 (i.e. program ended normally). In C++ while you cannot have void main() you still can skip the return 0; at the end if you don’t want to type it yourself.
