Structural Design Patterns in Modern C++ - Adding Buffering to Streams

The video tutorial discusses file I/O operations, focusing on the need for buffering to enhance efficiency. It highlights client requests for buffering and explains why implementing it in existing classes would violate software design principles like the Open Closed and Single Responsibility principles. Instead, the tutorial suggests creating new classes to handle buffering, using inheritance to override methods. The session concludes with a preview of the next lecture.

What are the potential drawbacks of implementing buffering directly in the file output stream class?

Describe the process of how buffering is implemented in file output and input stream classes.
