In C++, yes, you do

    (&a == &b)

and the plain == is used for the common case of actually doing what you mean (what in Java would be .equals()).

Actually, that's not always correct in C++ (it is in C). It is possible that either type has the operator& overloaded, so instead the proper way to do it is:

    (std::addressof(a) == std::addressof(b))

Thanks (I didn't even know this operator was overloadable)!
