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++

## Base Class Constructor

When we make an instance of the `Derived` class without parameters it will first call the default constructor of the `Base` class and then the `Derived` class. In the same way, when we call the parameterized constructor of the derived class, it will first call the parameterized constructor of the `Base` class and then `Derived` class.

The following code explains how this is done:

IIn this lesson, we'll learn how constructors and destructors are called in derived and base classes during inheritance.
