Structural Design Patterns in Modern C++ - Introduction to the Proxy Pattern

The video tutorial explains the proxy design pattern, which acts as an alias for another object, providing additional functionality without modifying the original object. It discusses the importance of matching the proxy's interface with the real object to ensure seamless client interaction. The tutorial covers various implementation techniques, including inheritance and operator overloading in C, and introduces different types of proxies like virtual, cache, remote, protection, and smart proxies, each serving unique purposes such as on-demand object creation, caching, remote access, and access control.
