Structural Design Patterns in Modern C++ - Functional Decorator

The video tutorial explains different types of decorators: dynamic, static, and functional. It focuses on implementing functional decorators in C, which wrap functions to add extra behavior. The tutorial demonstrates creating a functional decorator using a function template and Lambda expressions. It shows how to apply these decorators to functions like square, add, and divide, and handle special cases such as division by zero. The video concludes with a discussion on limitations and potential improvements using the C20 standard.
