Answer 2

Basically overloading ++ is ambiguous since the compiler has no way to determine if you want pre- or post-increment. The solution the C++ Standards Committee came up with is to require a dummy parameter for post-increment (which is not used) .
This is really just a fudge to allow you to have 2 overloaded functions for the 2 cases. But that is the "official" way it is done.
