What is polymorphism in C++?

What is polymorphism 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).

Can you give me an example of polymorphism?

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

What are the types of polymorphism in C++?

There are two main types of polymorphism in C++: compile-time (or static) polymorphism, which includes function overloading and operator overloading, and run-time (or dynamic) polymorphism, which is achieved through inheritance and virtual functions.

How does polymorphism improve code flexibility?

Polymorphism improves code flexibility by allowing you to write more generic and reusable code. You can use base class pointers or references to work with derived class objects, making it easier to extend and maintain your code.
