面向对象程序课程设计任务书
指导教师：杨东鹤、陈巧红
商品名称和价格的管理，包括对商品和对应价格的增加、修改、删除、查找； 输入日期统计某天的销售情况并显示； 管理员可以根据订单编号查找删除修改某个订单,订单可以按照下单时间先后排序； 查看当天以及当月的所有订单。
顾客： 非会员和会员不同权限； 查看、选择、购买商品； 修改、删除、查找顾客购物车订单； 结账付款。
2、 文件系统分析 每天一个文档，文档名按照日期命名； 管理员账号、密码； 会员信息； 单个订单信息。
3、 对象分析 商店对象、列表对象、订单对象、订单管理对象、商品对象、购物篮对象、用户对象、管理员用户对象、顾客用户对象、时间日期对象、菜单对象、商品目录对象。 对象的合理抽象和封装，正确定义类之间的关系；
掌握类的概念、类的定义格式、类与结构的关系、类的成员属性和类的封装性； 掌握类对象的定义； 理解类的成员的访问控制的含义，公有、私有和保护成员的区别； 掌握构造函数和析构函数的含义与作用、定义方式和实现，能够根据要求正确定义和重载构造函数。能够根据给定的要求定义类并实现类的成员函数； 学会通过建立类及对象，用类的成员函数和对象访问类的成员； 学会利用建立类的构造函数，完成类的成员的初始化工作； 掌握单继承和多重继承的概念。 理解不同的继承类型：public、protected和private，掌握何时使用何种继承类型。 掌握类层次中构造函数的定义方式和建立对象时构造和析构次序。 掌握sort排序。 掌握封装变量基本权限设置原则。 掌握通过接口函数访问私有变量。 掌握重载类内运算符。 掌握重写父类函数、父类与子类之间相同函数名的调用。 掌握简单项目的研发； 掌握文件的读写方法； 掌握不同类之间的调用以及功能划分。
【题目】便利店管理系统
【目的】
通过设计一个小型的便利店管理系统，训练综合运用所学知识处理实际问题的能力，强化面向对象的程序设计理念，使自己的程序设计与调试水平有一个明显的提高。
【要求】
1、每个学生必须独立完成；
2、课程设计时间为1周；
3、设计语言采用C++；
4、学生有事离校必须请假。课程设计期间，无故缺席按旷课处理；缺席时间达四分之一以上者，未按规定上交实验报告的学生，其成绩按不及格处理。
【内容简介】
有一家小芳便利店，现在需要你为这个便利店开发一个简单的便利店管理系统，方便顾客自己购买商品，并提供对便利店销售情况的统计和管理功能。
【考核标准】
该系统为两种角色的用户提供服务，一种是便利店管理员，一种是顾客。便利店管理员根据账号、密码登录系统，顾客无需登录即可使用系统。
1、 顾客通过该系统购买商品，可实现多次购买一次性结账, 商品信息包括商品编号、商品名称、商品价格，商品包括普通商品和进口商品,进口同类商品价格是普通商品的1.2倍, 系统能够根据顾客的要求正确打印订单，订单内容包括订单编号、商品名称、商品的价格、商品数量、折扣等,显示进口商品名称时,在名称后加；管理员可以查看当天以及当月的所有订单,成绩≥60；
2、 系统退出后能保存当天的销售信息，要求每天一个文档，文档名按照日期命名。管理员可以根据订单编号查找删除修改某个订单,订单可以按照下单时间先后排序，成绩≥70；
3、 能够实现管理员对商品名称和价格的管理，包括对商品和对应价格的增加、修改、删除、查找，成绩≥80；
4、 系统可根据历史记录对销售情况进行统计，根据管理员的输入日期统计某天的销售情况并显示（包括一共销售多少单，销售额是多少，各种商品的销售情况），成绩≥90.
5、 有能力的话,可以考虑会员和非会员的情况.
要求：
用面向对象的程序设计方法设计该系统。本系统涉及的基本对象有订单对象、订单管理对象、商品对象、进口商品对象、购物篮对象、商店对象。实现对这些对象的合理抽象和封装，正确定义类之间的关系。界面合理，代码文件组织清晰，命名符合规范，代码注释清楚，课设报告书质量高。
