本文介绍了我需要为一家餐馆写一个程序。使用C.需要添加一些项目的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
问题：为餐馆写一个程序。您的程序应显示主菜单，允许客户在早餐菜单选项，午餐菜单选项，晚餐菜单选项和结账选项之间进行选择。从主菜单中选择一个选项后，您的程序应继续显示一个子菜单，该子菜单将显示所选食物的可用食物和价格。您的程序应允许客户选择食物并输入订单数量。您的程序应继续允许客户订购他们的食物，直到他们选择主菜单中的结帐选项，然后只有您的程序将显示订单列表，其中包含客户需要支付的数量，价格和总金额。 />
这是我的编码，我需要改进它以显示购买物品的收据，需要支付的总金额并允许用户输入现金金额要支付并计算他们的余额。请帮帮我。
Question : Write a program for a restaurant. Your program should display a main menu that allows the customer to select between the breakfast menu option,lunch menu option, dinner menu option and check out option. After selected an option from the main menu, your program should continue to display a sub-menu that will show the available foods and prices for the selected meal.Your program should allow the customer to select the food and enter the order quantity. Your program should continue to allow the customer to order their food until they select the check out option in the main menu,then only your program will display the order list with the quantity, prices and total amount need to pay by the customer.
This is my coding and I need to improve it to display a receipt of items purchased , the total amount need to be paid and allow the user to enter the cash amount they are going to pay and calculate the balance for them. Please help me.
