Clients submit the orders through the application. The orders are delivered in a first-come-first-serve order.

Task 1.1: Draw a class diagram that includes the following classes:

Class client that stores the following information about clients: ID, Name, address, mobile number, rating.

Class order that stores the following information about every order: Client (person who made the order), restaurant ID, Restaurant name, order description.

Class System that includes the following: linked list of all clients, queue of all orders.

Class ordersQueue: that includes the following: queue implementation over a doubly-linked-list, including all of the queue operations, the queue should take orders inside.

Notes:

There is composition between class order and client.

You need to modify class DLL to make the nodes and all basic operations take client object and not integers

DLLNode should include: client, and node pointers prev and next.

Use the same DLL class you modified, and create a list of clients in the main method in class system (the main class in your project)

Now, modify another copy of DLL, that contains orders objects, now you are ready to use this DLL to build a queue for orders
