ATM取款机模拟——数据结构课设

   今天帮人写的第二篇课设 。 ;-) 机智的窝

    要求:大概说一下吧,就是要创建一个用户(初化一账户),模拟ATM的业务(取款,100的整数倍,改密               码,查剩余金额。等等,各种简单繁琐的操作 ;-) 

   直接贴代码吧:

#include <iostream>
#include <cstdlib>
#include <cstdio>
#include <cstring>
#include <string>

    bool check_passwd(char n[],char pwd[]); // 核对password
    void change_passwd();     // 改动password
    void fetchmoney();        // 取款
    void information();            // 查询信息
    void exitATM();            // 退出系统
    void functionshow();      // 功能界面
    void lock();              // 锁机
