Heterogeneous Collections in C++

This lecture covers the implementation of heterogeneous collections in C++, focusing on different design approaches and considerations. The instructor explains the concepts of managing pointers internally or externally, the ownership of objects in the collection, and the importance of polymorphic copying. Practical examples are provided to illustrate the implementation of heterogeneous collections, emphasizing the clean and direct design choices for users of the class. The lecture concludes with recommendations on managing memory and object ownership in heterogeneous collections.
