Structural Design Patterns in Modern C++ - Implementing and Applying Streams

The video tutorial introduces the decorator pattern and demonstrates its application by creating a file stream library. The library includes input and output stream classes for reading and writing files. The tutorial covers the implementation of these classes, including constructors, methods for file operations, and error handling. It concludes with testing the implementation and discussing potential extensions to other stream types.

How does the output stream clause differ from the input stream clause?

What is the role of the destructor in the input stream class?

What are the potential types of streams that can be implemented beyond file streams?
