Behavioral Design Patterns in C++ - Introduction-Command

The video tutorial discusses the Command design pattern, emphasizing its importance in UI-based applications for separating the user interface from core functionality. This separation allows independent modification but introduces challenges in transforming user input into application requests. The tutorial explains how callbacks can reduce dependency on function names, allowing runtime invocation. However, simple callbacks can be complex for tasks like undo/redo. The Command pattern addresses this by converting functions into objects, enabling state management and macro commands. The tutorial concludes by highlighting the pattern's intent and benefits.
