Lecture 18: More on C++ Classes: Constructors, Abstract Data Types, Friends and Arrays

This video briefly reviews the introductory objects and classes topics from our previous video. Then, we introduce constructors and the default constructor as tools to help us initialize the private variables in our classes. We also explain how classes can be used to make abstract data types (ADTs) and the important advantages of using ADTs. Next we cover friend functions and how to give non-member functions access to data in a class. Finally, we review how to use arrays of objects, paying close attention to whether we have access to private data or need to use a member function like a getter or setter. For additional review of classes, please also see our previous video introducing objects and classes. Note: these videos are original lecture recordings I have been making for my own classes and am sharing here in case they may be helpful to others as well. These videos are currently a work in progress over the course of the semester. I welcome your comments and feedback.
