活期储蓄账目管理系统-管理员版
设计菜单，以便进行人机交互，选择对应的功能来实现。主菜单应该包括主要的功能以及简单的介绍和退出功能。在主菜单打开之前应该是一个登陆界面只有当管理员账号和密码输对的时候才能进入系统进行操作，在存取款和查找交易记录时只有输入的卡号和密码正确时，才可以进行操作。这样才能保证安全性。在查找交易记录时应该包含时间、用户名、卡号、存入或取出的金额等信息。综上所诉需要构造3个类或者结构体，分别存储管理员账号信息，用户账号信息，存取款信息。为了程序的模块化，应该使用构造函数来避免重复累赘的代码，例如检查密码是否正确的函数，还有搜索卡号是否存在的函数等等。程序流程概要图 详细设计 1. 创建记录信息的结构体包含姓名，卡号，金额，时间等。 2. 创建用户类包含用户的姓名，卡号，密码，账户余额等，重载其输入输出运算符。创建管理员类，使管理员类继承用户类，表明管理员本身也可以是用户。构造函数：根据输入的卡号查询卡号是否存在，如果存在返回它的标识，否则返回 -1。 验证密码函数：根据查询卡号函数返回的标识，找到相应卡号的密码，将密码与输 入值对比，如果相同则进项下一项，如果不同则递归调用本身让使用者重新输入 密码。构造显示所有账户信息的函数，用 for 循环进行遍历输出。主函数：首先用 do-while 循环构建等会界面，让用户输入管理员用账号密码，直 到输入正确时停止循环进行下一步。再次使用一个 do-while 并通过使用 switch-case 函数进行功能选择。用 fstream.h 中的对应在开户，销户，存取款时对 user.txt 中的内容进行修改，在显 示所有用户信息时对 user.txt 文件进行读取，在查询记录时 record.txt 文件中的内 容进行读取。 源代码
