Structural Design Patterns in Modern C++ - Adding the Abstract Decorator Class in Stream Class Hierarchies

The video tutorial explains the transition from inheritance to composition in stream classes, highlighting the limitations of the current structure. It introduces the decorator pattern as a solution to enhance flexibility and functionality, allowing for the combination of features like buffering, encryption, and compression. The tutorial provides a detailed walkthrough of implementing the decorator pattern, including creating new decorators and managing features dynamically at runtime.

What is the main issue with the compressed output stream in relation to the file output stream?

How can the compressed output stream be modified to enhance its flexibility?

Describe the process of combining features of different streams using the decorator pattern.

Explain how the decorator pattern is implemented in the context of output streams.

How does the decorator pattern allow for the addition and removal of features at runtime?

What are the implications of using an abstract class for output decorators?

What advantages does the decorator pattern provide over traditional inheritance?
