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.

What is the purpose of creating a fixed-size buffer in the simulation?

• To simulate the concept of buffering

• To reduce memory usage

• To actually store data temporarily

• To increase the speed of data processing

In the buffering simulation, what happens when the buffer is full or when 'close' is called?

• The buffer is flushed

• The buffer is discarded

• The buffer is expanded

• The buffer is ignored

How does the open-closed principle benefit software design?

• By enabling the addition of new features without altering existing code

• By reducing the number of classes

• By allowing modification of existing classes

• By making software faster

What is the main reason for implementing encrypted streams?

• To compress data

• To enhance data security

• To improve data transfer speed

• To simplify data processing

What happens to data during the read operation in encrypted streams?

• It is compressed

• It is decrypted

• It is ignored

• It is duplicated
