Whenever the user starts up the application, both lists will always be empty and when they close the application, they'll lose their lists. When the user starts the program, they will be presented with a menu of options, including the option to view either list, to add a new item to the todo list, to mark an item as completed, or to exit the program. numbering the choices in the menu to provide the user with an easy way to choose their preferred option. When an item is marked completed, it is removed from the todo list and is added to the list of items that have been completed. The program should not end until the user tells it to end.
