This is probably a simple question to answer but I''m curious. In C++, can you have a pointer to an instance of any class? Like you have two separate classes and want a pointer to be able to point to either one of the two. do you declare it as a (void*)or what? -iGore Productions-

The only way to do exactly what you want is through a void pointer, yes. However, you can have a base class that a set of classes are derived from, and then use a pointer to the base class type to point to any of the derived types.

Or, if you designing the classes yourself then the clean way to this is to create a new class that both your classes inherit from. That way you are sure that the pointer can be used for only those classes and not everything else.
