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++

## Multiple Inheritance

We can inherit the base class attributes to the derived class if we want derived class to have access data members and member functions of the base class. But to inherit multiple classes data members and member functions to the derived, the concept of *multiple inheritance* comes in. We can inherit multiple classes as base classes separated by `,`
```C++

class Derived : public Base1 , public Base2 , ...
 
```
### Example

Let's take the example of `Vehicle` and `Car` classes which acts as the base classes of the `Honda` class:
