Behavioral Design Patterns in C++ - TextPad - VII

The video tutorial discusses the initial tight coupling between a menu and an application class due to direct method invocation through pointers. To address this, function pointers and bind were used to decouple them, allowing the menu to be reused with other classes. However, this approach was inflexible, leading to the introduction of the command pattern. The command pattern involves creating a Command interface with an execute function, allowing any class inheriting from Command to handle menu requests, thus enhancing flexibility and eliminating the need for function pointers and bind.
