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.

Aggregation is very similar to composition. It also follows the **Has-A** model. This creates a parent-child relationship between two classes, with one class owning the object of another.

So, what makes aggregation unique? 

# Independent Lifetimes

> In aggregation, the lifetime of the owned object does not depend on the lifetime of the owner.

The owner object could get deleted but the owned object can continue to exist in the program. In composition, the parent **contains** a child object. This bounds the child to its parent. In aggregation, the parent only contains a **reference** to the child, which removes the child's dependency.

In this lesson, we'll learn a new way of linking different classes.
