Structural Design Patterns in Modern C++ - Adding the BufferedStream Class

The video tutorial discusses the implementation of buffering in file output and input streams. It explains that actual buffering is not implemented but simulated to keep the code simple. The tutorial covers creating a fixed-size buffer, simulating write and read operations, and adhering to the open-closed principle by adding new classes for new features. It also touches on future enhancements like encrypted streams for handling confidential data.

How does the implementation of buffered input and output streams enhance data handling?

Describe the process of implementing encryption and decryption in the stream hierarchy.
