Part 4 - Menus and Confirmations
The main subject matter of this part is constructing menus. Getting confirmations from the user is covered, too.
Figures 4-1 - 4-5. should give you an idea of the menu that you'll have to implement. Functionality is needed only on items Exit and Change Product Info. These should have the same functionality as the equivalent buttons. There is a way to avoid writing separate event handling for buttons and menus. Hopefully you can figure it out.
Implement an exit confirmation as shown in the figure 4-6.
