Why does an overridden function in the derived class hide other overloads of the base class?
... drastic shift in overload resolution results.
For example, let's say the base class B has a member function foo that takes a parameter of type void *, and all calls to foo(NULL) are resolved to B::foo(void *). Let's say there's no name hiding and this B::foo(void *) is visible in many different cl...

Why do we need virtual functions in C++?
