Actually virtual meaning is which doesnot exist in the real world. Here virtual base class means which has virtual member function but defined in derived class.

virtual classes are generally used in hybrid inheritance for exp:Their are two classes B & C derived from publically from A and in turn a class D has been derived from class B & C so to avoid the inheritance of multiple copies of certain function in A into D through B & C virtual classes are used.

It is very much useful in hybrid inheritence.

By declaring the class we can get only one copy of it when it was inherited.

If we are working with multiple inheritance, it is always better to make the base class as virtual inorder to avoid the multiple copies of the base class data. :)

Suppose you have two derived classes B and C that have a common base class A, and you also have another class D that inherits from B and C. You can declare the base class A as virtual to ensure that B and C share the same subobject of A.
