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++

If we want to inherit data members and member functions of the base class which is already inherited from another class, the concept of multilevel inheritance comes in. This contains a more hierarchical approach.

```c++
class parent
class child : public parent
class grandChild : public child
```
# Example #
Let’s take the example of `Vehicle` class which acts as a parent to `Car` class. Now `Car` class acts as a parent to `Honda` class.
