Behavioral Design Patterns in C++ - Undo - II

The video tutorial explains the command pattern, focusing on how it can be used to manage user actions in an application. It discusses the use of a stack to store changes for undo operations and highlights the limitations of storing function calls directly. The command pattern is introduced as a solution, converting functions into objects that can store state and be undone. The tutorial demonstrates how command objects are implemented and used to support undoable operations, emphasizing the benefits of this approach in application development.
