Behavioral Design Patterns in C++ - TextPad - V

The video addresses the issue of tight coupling between the menu and application classes, making it difficult to reuse the menu with other classes. The instructor explains the concept of function pointers and the challenges of using them with member functions. To resolve this, the menu class is modified to allow runtime configuration using a map and tuples to store options and callbacks. The video concludes with implementing a callback mechanism and testing the menu's functionality, ensuring it can handle user input and execute the appropriate functions.

What is the significance of using a tuple to store callback information?

Describe the process of invoking a function as a callback in the menu class.

What checks does the teacher implement to validate user input in the menu?
