Object-oriented programming (OOP) has been around for decades. If you have a basic understanding of C++ and are interested in leveling up your skills, this class will help you do just that. 

Starting with an overview of the basics, you’ll dive into understanding the time-honored technique for implementing complex applications using user-defined classes. Followed up by discussing classes and objects, and then building up to the high-level topics including inheritance and polymorphism. 

Throughout the course, you’ll be fully immersed in OOP for C++, with illustrations, exercises, quizzes, and hands-on challenges every step of the way. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

> The word **Polymorphism** is a combination of two Greek words, **Poly** means *many* and **Morph** means *forms*.

# Definition
When we say *polymorphism* in programming that means something which exhibits many forms or behaviors. So far, we have learned that we can add new data and functions to a class through inheritance. But what about if we want our derived class to inherit a method from the base class and have a different implementation for it? That is when polymorphism comes in, a fundamental concept in OOP paradigm.

# Shape Class

We are considering here the example of **Shape** class, which is base class for many shapes like *Rectangle and Circle*. This class contains a function **getArea()** which calculates the area for the *derived* classes.



In this lesson, we will be learning about the basics of polymorphism with the implementation details.
