A developer wants you to develop a simple take away restaurant order service. The system reads from a file containing information about the restaurant (such as the name, place and menu). The system then allows the user to login into the system. Once the user is successfully login, a user is able to see the menu. A user can then use the system to place an order from the particular restaurant. The system can alerts the restaurant. Eventually, the restaurant prepares the ordered menu and delivers them to the customer.
