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.

# A Real Life Example
For the sake of explanation, we'll start off by creating a simple `movie` class which contains three members:

class Movie{
  string title;
  int year;
  string genre;

  public:
  Movie(){
    title = "";
    year = -1;
    genre = "";
  }

  Movie(string t, int y, string g){
    title = t;
    year = y;
    genre = g;
  }
};

There must be a way to interact with the `title`, `year` and `genre` variables. They hold all the information about a movie, but how do we access or modify them?

We could create a `getTitle()` method which would return the title to us. Similarly, the other two members could also have corresponding `get` functions. 

By observing the emerging pattern, we can make a definitive conclusion. These functions should be part of the class of itself! Let's try it out.

This lesson shows us how to implement the first component of data hiding: encapsulation.
