This lecture covers the fundamental concepts of multiple inheritance in object-oriented programming, including encapsulation, abstraction, classes, polymorphism, and virtual classes. It also discusses the challenges and solutions related to multiple inheritance, such as name attribute/method collisions and the use of virtual classes to prevent multiple inheritance. The lecture provides practical examples and explanations on how to implement multiple inheritance in C++, emphasizing the syntax, order of constructor/destructor calls, and the semantic meaning of multiple inheritance. Additionally, it explores the use of diamond diagrams, virtual inheritance, and the resolution of naming conflicts. The lecture concludes with a detailed analysis of case studies and coding exercises to reinforce the understanding of multiple inheritance.
