面向对象程序课程设计（2014/2015学年第一学期第20周）指导教师：庄巧莉、杨东鹤班级：计算机科学与技术13（1）学号：姓名：面向对象程序课程设计目录一、题目二、需求分析三、系统结构图四、类的设计五、程序代码与说明六、运行结果与分析七、心得与体会一：题目自助点餐系统二：需求分析有一个小型餐厅，该餐厅提供即时就餐和外卖服务。

现在这个餐厅打算使用自助点餐系统，让顾客自己点餐，实现以下功能。

1、根据顾客的选择正确打出账单2、正确统计出每一天的及时就餐和外卖的销售情况3、实现对餐厅菜式和价格的有效管理4、考虑点餐的自动排序问题，使顾客可以实时查询到自己菜单处理情况三：系统结构图四：类的设计Client类：客户类，包含客户属性姓名，电话号码，费用等信息，登记客户，记录客户订单信息ClientManager类：客户管理类，用于管理客户，记录客户数量，存储客户菜单信息，查询客户订单信息，统计订单FeeManager类：用于记录就餐、外卖的销售费用，统计收入Food类：餐厅食物的类，包含食物名称和价格FoodManager类：管理菜单，用于添加食物，修改食物，删除食物，记录不同食物的信息，呈现菜单MenuView类：用于打印各种操作界面五：程序代码与说明Client.h#ifndef CLIENT#define CLIENT#include"FoodManager.h"#include<iostream>using namespace std;class Client{private:int number;//客户编号int type;//客户的类型，1表示就餐，2表示外卖double fee;//客户账单费用char *name;//客户名称char *phone;//客户手机号码public:Client(){}//构造函数char * getName();//返回客户姓名int num[100];//num[i]存储食物数量,i表示食物编号FoodManager client_fm;
