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++

We have learned that we can implement *inheritance* which will result in avoiding **redundant coding** and will also save the programmer's *time and effort*.

### Avoiding Duplication of Code
Considering the previous example, if we have to implement another class for `MoneyMarketAccount` we **don't need to duplicate** the code for the `deposit()` and `withdraw()` methods inside this new Class because we can inherit and use the parent class's methods. In this way, we can avoid the *duplication of code*.
