C++ Abstract base classes and pure virtual functions [7]

You cannot create an instance of an abstract base class, but you can create other classes that are derived from it. A pure virtual function is a virtual member function that belongs to a base class and needs to be redefined in derived classes. When a class has a pure virtual function as a member, it becomes an abstract base class.
Learn how this works through writing sample classes in this C++ tutorial for beginners written with Visual Studio 2022 C++ .

Now this concept is my academic weapon for the OOP theory exam. Loved it

Love your content hank, is there anyway you could use AI to show examples where it makes mistakes or why it's important to utilise it's advantages

Thanks tons for the comment. I am planning to do some more stuff with A.I. in the future, but haven't been able to get to it yet. It's on the stack of stuff though. In the meantime, I do have an A.I. play list I used for my classes at CSUEB. You can find some answers to your questions in those videos, at least implicitly.

Hi! I don't understand why you made the print function virtual in the derived classes.

@ProfessorHankStalica Жыл бұрын

You don't have to do so. I do so out of habit to remind me that it is a virtual function in case I want to use the class as a base class for other classes. Basically as a form of documentation. You absolutely don't have to though.

Hmm never seen virtual functions and that const before

@velvethamster9809 3 ай бұрын

virtual keyword in a function within class means, that function can be overridden by its derived classes. const keyword after the function parameter within a class means the function can not modify its class members.
