Behavioral Design Patterns in C++ - TextPad - VIII

The video tutorial discusses the transition from using function pointers to a command pattern in a software design. It introduces a command base class with a virtual function 'execute' and explains how this change allows for more flexible and decoupled code. The tutorial covers modifications in the application class to inherit from the command class and implement the execute method. It highlights the advantages of this design, such as easier method invocation and potential for undo functionality. The final design is presented through a class diagram, emphasizing the separation of concerns between the menu (invoker) and application (receiver).
