Structural Design Patterns in Modern C++ - Applying Virtual Proxy

The video tutorial explains the concept of a bitmap proxy, which inherits from an image class to maintain the same interface as a bitmap. It covers the use of inheriting constructors to simplify implementation and the importance of a destructor for managing bitmap instances. The tutorial demonstrates how to check if a bitmap is loaded, how to load it conditionally based on the file name, and the benefits of using a proxy to avoid expensive loading processes. It concludes with a class diagram illustrating the interaction between the client, bitmap proxy, and bitmap.
