In C++, what is a virtual base class?

Question

I want to know what a \"virtual base class\" is and what it means.

Let me show an example:

class Foo
{
public:
    void DoSomething() { /* .

Virtual classes are not the same as virtual inheritance. Virtual classes you cannot instantiate, virtual inheritance is something else entirely.

Wikipedia describes it better than I can. http://en.wikipedia.org/wiki/Virtual_inheritance
