Which `main` is used if I specify more than one

Question

Along with a couple of others, the following are valid prototypes for main():

1. int main(void)

2. int main(int, char**)

In C we can't overload functions so it's never possible to have both. But in C++ that's not true. If I were to have both in a compiled C++ executable, then which one is used? Does it depend on the command line? What does the standard say?

Answer 1

C++11 §3.6.1/2:

” This function shall not be overloaded.
