Lecture
This lecture covers the concept of polymorphic display in C++, where all products can be displayed in their own unique way by utilizing polymorphic methods defined at the superclass level. It explains how to define default display behavior, finalize a product class by setting a base value that cannot be changed, and create an abstract product class. The instructor demonstrates the implementation of polymorphic display through code examples and emphasizes the importance of abstraction in object-oriented programming.
