Скачать или смотреть 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++ .
