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.

What is the main issue with creating an instance of Buffered Encrypted Stream in C?

How can we ensure that both Encrypted Stream and Buffered Output Stream inherit from File Output Stream without causing issues?

Discuss the implications of not being able to reuse features for a new kind of stream, such as Network Stream.

Explain the concept of using wrappers in the context of adding features to components.

What are the limitations of using inheritance for mixing features in class design?

What changes need to be made to the Compressed Stream to avoid the problems associated with inheritance?

What is the significance of ensuring that the Compressed Stream is a kind of Output Stream?
