Object-oriented programming (OOP) has been around for decades. If you have a basic understanding of C++ and are interested in leveling up your skills, this class will help you do just that. 

Starting with an overview of the basics, you’ll dive into understanding the time-honored technique for implementing complex applications using user-defined classes. Followed up by discussing classes and objects, and then building up to the high-level topics including inheritance and polymorphism. 

Throughout the course, you’ll be fully immersed in OOP for C++, with illustrations, exercises, quizzes, and hands-on challenges every step of the way. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

The private data members of a class are only accessible through the functions present in that class. Nothing from outside can manipulate the class object without using its functions. 

What if we need to access class variables in a function which is not a part of the class? That function would have to become a **friend** of the class.

> A friend function is an independent function which has access to the variables and methods of its befriended class.

To create a friend function for a class, it must be declared in the class along with the `friend` keyword.  

Let's create a `Ball` class to explain this better:

We'll take a look at a special category of functions called friends.
