C++ Polymorphism and Virtual Function

In this article an introduction to C++ Polymorphism and Virtual functions is discussed. Virtual function is a special function which is used for implementing Polymorphism techniques. It means that polymorphism is achieved through the use of virtual function. The polymorphism is the most important feature of object-oriented programming (OOP).
