Structural Design Patterns in Modern C++ - Basic Example - Decorator Design Pattern

The video tutorial explains the implementation of a component base class, a concrete component, and a decorator hierarchy. It discusses the creation of concrete decorators directly from the component class, bypassing a decorator base class. The tutorial demonstrates how to use these decorators in the main function, emphasizing the order of operations and the necessity of the base component. The tutorial concludes with a discussion on generating a class diagram to visualize the relationships.
