Polymorphism is possible in C language. What is the difference between const int*, const int * const, and int const *? It is usually used in the context of late binding, where the behavior of an object to respond to a call to its method members is determined based on object type at run time. Why do you say "air conditioned" and not "conditioned air"? General and Gameplay Programming Programming.

"I am really not into it" vs "I am not really into it". Polymorphism, therefore, is the ability for objects of different classes related by inheritance to response differently to the same function call. Polymorphism is an important concept in OOP. For implementing encapsulation, which is binding between data and functions, pointers to functions are used. In case of using abstract class or function overloading, which function is supposed to be called first? It is achieved when the function to be invoked is known at run time. Polymorphism means the ability to take different forms. In C++, polymorphism, generally happens because of classes objects and events are related with inheritance and hierarchy.
