Polymorphic class:
Virtual functions support dynamic binding and object-oriented programming. 
A class that declares or inherits a virtual function is called a polymorphic class.

Abstract class:
An abstract class is a class that can be used only as a base class of some other class; 
no objects of an abstract class can be created except as subobjects of a class derived from it.
A class is abstract if it has at least one pure virtual function.
