Object-Oriented Programming: Polymorphism

This lecture introduces the concept of polymorphism in object-oriented programming, focusing on heterogeneous collections, pure virtual methods, abstract classes, and the implementation of polymorphic treatments. The instructor explains the use of virtual methods, override, and the subtyping relation. Through a case study, students learn about the implementation of polymorphism in C++, including the creation of abstract classes and the design of polymorphic treatments. The lecture also covers the application of polymorphism in a hotel reservation system, where different types of services are modeled using polymorphic behavior.
