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.

# Custom Objects

In C++, we have several different data types like `int`, `string`, `bool` etc. An object can be created out of any of those types. An *object* is an instance of a class. Well, object-oriented programming wouldn't make sense if we couldn't make our own custom objects. This is where **classes** come into play.

Classes are used to create _user-defined data types._  We can use these basic data types to create our own class. The cool part is that our class can contain multiple variables, pointers, and functions which would be available to us whenever a class object is created.

Let's start off with an example of a **car** class. Below, we can see that a car object would contain:
