BCA - OOPS and Data Structures

In C++, polymorphism allows objects to behave differently even though they are accessed using the same function name. 

There are two types of polymorphism in C++: 

    Compile Time Polymorphism 
    Runtime Polymorphism

1. Compile Time Polymorphism 
   
   Also called Early Binding  or Static Polymorphism  
   
       This type of polymorphism is resolved at compile time  — meaning the compiler already knows which function will be called. 
   
   By using: 
   
       Function Overloading 
       Operator Overloading
2. Runtime Polymorphism 
   
   Also called Late Binding  or Dynamic Polymorphism  
   
       This type of polymorphism is resolved at runtime  — the actual object determines which function is called.
   
   By using: 
   
       Virtual Functions 
       Base class pointer/reference to derived class object
