The word polymorphism means having many forms. In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form. A real-life example of polymorphism, a person at the same time can have different characteristics. Like a man at the same time is a father, a husband, an employee. So the same person posses different behavior in different situations. This is called polymorphism. Polymorphism is considered one of the important features of Object-Oriented Programming.
In C++ polymorphism is mainly divided into two types:
Compile-time Polymorphism
Runtime Polymorphism
