Structural Design Patterns in Modern C++ - Adding Encryption and Compression Support to Streams

The video tutorial covers the implementation of stream classes with buffering, encryption, and compression features. It explains the hierarchy of output and input stream classes, and demonstrates the implementation of encryption and decryption by altering ASCII values. The tutorial also discusses compression and decompression using libraries, and tests these features. Finally, it explores combining features like encryption, compression, and buffering using multiple inheritance in C programming.

Explain the process of compression and decompression in the implemented classes.

What challenges arise when mixing encryption, compression, and buffering in stream classes?
