本文实例为大家分享了C++实现会员管理程序的具体代码，供大家参考，具体内容如下
设计快捷店会员的简单管理程序。基本要求如下：
（1）定义人民币RMB类，实现人民币的基本运算和显示。
（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，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类数组或链表，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；
② 已有会员充值；
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，营业额（收、支情况）。
