任务:模拟银行ATM机,要求界面友好
首先我们对这个问题进行分析:
* 模拟ATM机,实现以下功能:1.查询余额 2.存款 3.取款 0.退出(要求整存整取)
* 要求界面友好。
系统设计:
* 模块分化,确定各模块的功能及输入/输出
* 1.showMenu模块
* 功能:显示菜单功能,读取用户的操作系统
* 输入:无
* 输出:返回用户输入的功能选择
* 2.getMoney模块
* 功能:查询用户账号的余额。
* 输入:无
* 输出:返回用户账号的余额
* 3.deposit(存储)模块
* 功能:根据用户输入的钱数进行账号余额的增加
* 输入:待存的金额
* 输出:无
* 4.withdraw模块
* 功能:根据用户输入的钱数进行余额的减少,如果余额不够则提示不能完成此操作。
* 输入:待取的金额。
* 输出:无
代码显示:
头文件.h
#include<stdio.h> #include<stdlib.h> //函数声明 int showMenu(); double getMoney();
void deposit(double temp); void withdraw(double temp);
