What is polymorphism in C++ classes?

Can you explain what polymorphism is in C++?

Polymorphism in C++ allows methods to do different things based on the object that it is acting upon. It enables a single interface to represent different underlying forms (data types).

How does polymorphism work with classes?

In C++, polymorphism is typically achieved through inheritance and virtual functions. A base class defines a method, and derived classes override that method to provide specific implementations.

Can you give me an example of polymorphism in action?

Sure! Consider a base class Shape with a virtual method draw(). Derived classes like Circle and Square implement their own versions of draw(). When you call draw() on a Shape pointer that points to a Circle, it will execute the Circle's draw() method.

What are the benefits of using polymorphism?

Polymorphism enhances code reusability and flexibility. It allows you to write more generic code that can work with different types of objects, making your programs easier to maintain and extend.
