please solve quickly and use c++

For all the problems, please create a main function to test the functionality of the three classes. Given that you create a menu to input the order, it will be considered a bonus. Bonus: The restaurant wants to operate in fully digital mode to reduce the amount of paper used in the ordering process and to let the waiters focus only on delivering food by allowing user to view the Menu and place the orders by themselves without having the Waiters place the orders. It is required to do the following: 1- UML Design and implementation for new classes: User, and Menu. 2- Redesign the orders' class to include overloaded or new functions to the order class without the need of the functions belonging to the waiter. Helpful information: The phrase "This function in waiter class may be used in conjunction with another function in order class means that you have to include an object of the order in the waiter class". It is not restricted to use this mechanism but highly recommended.
