运行结果与分析
一种是餐厅管理员，一种是顾客。餐厅管理员根据账号、密码登录系统。顾客无需登录即可使用系统。
考核标准>=60:
菜单以文件形式保存：
保存菜单代码如下：
读取food文件代码如下：
在店用餐顾客服务：
在店消费的订单信息：
订单内容包括订单编号、菜品名称、每个菜品的价格、份数、折扣等
在店消费要求包括餐桌号，是否有包厢费
这两项目的已达成
外卖就餐
订单内容包括订单编号、菜品名称、每个菜品的价格、份数、折扣等
外卖要求包括送餐时间，送餐地点，客户手机号，外卖服务费
考核标准>=70:
系统退出后能保存当天的订单信息，要求每天一个文档，文档名按照日期命名
订单按照下单时间先后排序
输入日期为2020-6-1
Data文件夹中出现2020-6-1order 文件 该文件中保存了订单信息
保存当天订单的代码如下：
餐厅管理员可以根据订单编号或手机号查找、删除或修改某个订单
查找
订单号查找：
手机号查找：
修改
删除订单：
考核标准>=80:
能够实现对保存在文件中的餐厅菜式和价格的管理，包括对菜品和对应价格的增加、修改、删除、查找，折扣的设置，设置后，顾客在点餐时看到的是新设置后的菜单，成绩≥80；
增加菜品
修改价格
删除
折扣设置/修改
查找：
查找操作已经包含在菜品和对应价格的增加、修改、删除、折扣的操作中，且每次修改后均会展示菜单，故我未专门添加查找操作
顾客在点餐时看到的是新设置后的菜单：
首先会保存在food文件中，之后会从文件中读入展示给顾客新的菜单
考核标准>=90:
系统可根据历史记录对销售情况进行统计，根据餐厅管理员的输入日期统计某天的销售情况并显示
输入日期统计某天销售情况并显示
一共接了多少单，销售额是多少，各个菜品的销售情况，外卖和在店销售的占比
心得与体会
经过该次C++的课程设计，我更加深刻掌握了继承，STL容器等多种使用方法。更加深入了解巩固面向对象的思维。学会了在设计程序时要先需求分析，了解用户的使用需求，之后进行类的设计，最后再根据类的设计，进行代码的编写。在代码编写中也产生了许多的bug，但通过一次又一次的试验，将bug解决，同时也学会了很多的内容和知识，在遇到无法解决的问题时，通过查阅博客，查看书本等方法来解决问题。在解决bug过程中，对所学的内容也进行了复习和进一步的巩固学习，提高了自己的技能。
