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.

Learn Object-Oriented Programming in C++

In C++, we can impose access restrictions on different data members and member functions. The restrictions are specified through **access modifiers**. Access modifiers are tags we can associate with each member to define which parts of the program can access it directly.

There are three types of access modifiers. Let's take a look at them one by one.

# Private
A private member cannot be accessed directly from outside the class. The aim is to keep it hidden from the users and other classes. It is a popular practice to **keep the data members private** since we do not want anyone manipulating our data directly. By default, all declared members are private in C++. However, we can also make members private using the `private:` heading.

In this lesson, you will learn about the private, public and protected members.
