Reviews

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.
