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've learned that the data members contain all the information we store in a class. All the data members have to be defined at compile time. 

Data members should be defined as **private**.

## Data Types of Member Variables

C++ gives us a lot of freedom in selecting the data type of a data member. We can choose any of the in-built types such as `int`, `double` etc. Arrays, vectors, and pointers can also be used. The object of our custom class could have a number of arrays and variables! pretty cool right?

Here's an example of a  `Student` class and its data members:
