does c++ standard prohibit the void main() prototype?

Why is C++ not letting me do void main()? It's not much of a problem, but I'm still curious.

Answer 1

Because return type of main()(as mandated by the Standard) must be int

C++03 [Section 3.6.1 Main function]

An implementation shall not predefine the main function. This function shall not be overloaded. It shall have a return type of type int, but otherwise its type is implementation-defined.
