Question

You has been requested to design and develop a food ordering system based on following requirements:

The system shall allow the user to place an order for the food(s), view the food details, modify or delete the details of the food if necessary. Your program should be menu driven, giving the user various choices. You shall design the system by demonstrating the full understanding of object-oriented and use of list/link-list concept.

For every food order, the following information will be stored: Order ID (Auto assigned, unique ID), Food Code, flavor (example: Strawberry, chocolate), weight (Kg), Unit Price, Qty and customer information who order this cake. The customer information consists of customer ID, name, address and contact number. The order ID shall be automatically assigned with a unique ID when new order is added. The system shall display additional information that is amount (unit price * qty) when viewing the order details.

*in C++ language .
