+Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions. In C++ we have two types of polymorphism:
+1) Compile time Polymorphism – This is also known as static (or early) binding.
+2) Runtime Polymorphism – This is also known as dynamic (or late) binding.
