Explore OOP in C++ to write cleaner, modular, and scalable code. Learn classes in C++, data hiding, encapsulation, abstraction, inheritance, and polymorphism in C++.

Become  a C++ Programmer

This module aims to teach us how to write cleaner, more modular, and scalable code in C++ by providing an understanding of OOP in C++. We'll start with the basics of object-oriented programming and build up to advanced concepts such as inheritance, data hiding, and polymorphism. Along the way, we'll explore how each concept applies to C++ and how various C++ features facilitate OOP.

Object-Oriented Programming in C++

Similar to functions, classes need to be created outside the `main()`. The written code of a class and its attributes are known as the **definition** or **implementation** of the class.

# Definition Template

In C++, we define classes in the following way:

In this lesson, we will learn about the first steps in creating a class.
