Structural Design Patterns in Modern C++ - Pros and Cons - Decorator Design Pattern

The video tutorial explains the Decorator pattern, a design pattern that allows adding new behaviors to objects dynamically, unlike inheritance which adds behavior statically. It highlights the advantages of using the Decorator pattern, such as promoting loose coupling and avoiding class explosion. The tutorial also discusses scenarios where the Decorator pattern is useful, like adding functionalities to legacy systems or UI components. Additionally, it compares the Decorator pattern with the Proxy pattern, emphasizing the differences in behavior addition and coupling. The video concludes with a summary of when to use each pattern.
