Polymorphism is a object oriented concept which enables an object in two or more forms.  
 
There are 2 types of polymorphism 
1.compile time 2.run time 
Compile time : The compiler decides that it can invoke a form of an object ar compile time. 
 
Example In function overloading , the compiler decides which method to be invoked in complie time itself. 
 
Run Time: The complier comes to know about the object to be invoked in run time. 
 
Pure virtual functions. 
Based on the type of object the function which are overriden in child classes are invoked. Only the runtime decides what is the type of the object.

Polymorphism concept of using operators & functions  in different ways depending on  what they are  operating on.


Operators overloading : Using operators in differentways depending upon what they are operating on is called Operator over loading
