Structural Design Patterns in Modern C++ - Using Composition Instead of Inheritance

The video tutorial discusses the challenges of using multiple inheritance in C, particularly the issue of class explosion when combining features like buffering, encryption, and compression. It introduces the decorator pattern as a more flexible solution, allowing for runtime feature addition and removal without modifying existing components. The tutorial then demonstrates how to implement composition over inheritance, using a compressed stream as an example, and concludes with code changes to illustrate the concept.
