C++会员管理系统
一只代码鱼 人气:0本文设计C++快捷店会员的简单管理系统。基本要求如下:
(1)定义人民币RMB类(数据成员包括元,角,分三个整型变量),实现人民币的基本运算(对操作符+和-运算进行重载)和显示(显示元,角,分)。
(2)定义会员member类,表示会员的基本信息,包括:编号(按建立会员的顺序自动生成),姓名,密码,电话。提供输入、输出信息等功能。
(3)由RMB类和member类共同派生一个会员卡memberCar类(含有memberCar类型next指针变量),提供新建会员、充值、消费和查询余额等功能。
(4)main函数定义一个memberCar类链表,保存会员卡,模拟一个快捷店的会员卡管理功能,主要包括:
1)、 新建会员(检查输入的会员电话号码是否已经存在;若存在,则表示已经有该会员,需要重新输入会员信息),则为该会员建立会员卡,将该会员卡所表示的对象插入memberCar类链表表尾;
2)、已有会员充值(需要对充值进行非负性检查);
3)、已有会员消费(凭密码,不能透支);
4)、输出快捷店当前会员数,当前所有会员的消费总额,所有会员卡剩余的额度总数;
5)、遍历链表,输出所有会员卡的信息(不能输出会员个人密码);
6)、建立一个文本文件“member.txt”,将所有会员信息存入该文件中;
7) 、建立一个二进制文件“member.dat” ,将所有会员信息存入该文件中;
8) 、建立指针数组,初始化指针数组,存储链表中每个会员对象的地址;对链表中的每个会员按照消费额度按照从小到大进行排序(要求不能改变链表的逻辑结构),并将排序后的会员对象的地址存在指针数组中;
9)、利用(8)中的指针数组,在屏幕上输出会员的排序结果。
