This lecture covers the fundamental concepts of pointers and polymorphism in C++, including encapsulation, abstraction, inheritance, and the resolution of name collisions. It delves into the use of virtual methods, constructors, destructors, and operator overloading, emphasizing the importance of abstract classes and heterogeneous collections. Through examples, the instructor illustrates the dynamic resolution of method calls based on the actual instances during program execution. The lecture also explores the challenges of managing object ownership using pointers and smart pointers, culminating in a discussion on the complexities of object ownership. Practical applications are demonstrated through a project, showcasing the practical implications of working with pointers in C++.
