Polymorphism is one of the features of Object Oriented Programming (OOPS). C++ being Object Oriented language supports polymorphism. So let’s learn about it.
What is Polymorphism in C++?
Polymorphism itself means “many forms”. In C++ we can achieve this ‘many forms’ thing i.e Polymorphism in two ways.
- Function Overloading – Static Polymorphism
- Function Overriding – Dynamic Polymorphism
What is Static Polymorphism?
This Polymorphism happens during the compilation of the program.
- Implemented by Function Overloading.
- Also known as Static linkage or early Binding.
- The function call is associated with the function during compile time.
What is Dynamic Polymorphism?
This Polymorphism happens during the runtime of the program.
- Implemented by Function Overriding ( with the use of Virtual Function ).
- Also known as Dynamic linkage or late Binding.
- The function call is associated with the function during Runtime.
