一、题目描述

实现一个银行存取款管理系统，实现如下功能：

功能1：客户信息录入、包括编号、客户姓名、支取密码、客户地址、客户电话、账户金额； 功能2：存取款信息录入：即添加编号、日期、类别、存取数目、经办人；
功能3：根据客户信息查询存取款记录；客户信息和存取款信息的修改，删除；
功能4：信息保存、系统、退出；

二、程序思路

2.1 题目分析

要实现银行存取款管理系统，首先，我们应该想到定义一个结构体，包含姓名、卡号、地址等等个人信息，每一个客户就是一个结构体。那么所有客户信息、客户存取款记录应该怎么存呢？在本程序中我是用了两个动态扩容的顺序表存储的，客户信息按时间顺序连续存储在内存中，每一个客户的存取款记录也是连续存储的，当然，也可以使用两个链表是实现，并无多大差别，这些信息在退出程序时都应保存在文件中。

2.2 功能分析

能够输入和查询客户存款取款记录。在客户文件中，每个客户是一条记录，包括编号、客户姓名、支取密码、客户地址、客户电话、账户总金额；在存取款文件中，每次存取款是一条记录，包括编号、日期、类别、存取数目、经办人。类别分为取款和存款两种。本系统能够输入客户存款或取款记录；根据客户姓名查询存款和取款记录。

分步实施：

1、初步完成总体设计，搭好框架，确定人机对话界面，确定函数个数；

2、建立一个文件，输入客户的必要信息，能对文件进行显示、输入、修订、删除等。

3、进一步要求：完成客户姓名查询存款和取款记录，并能得到每次帐户总金额。

2.3 程序设计

定义三个结构体，第一个结构体是一个人所包含的信息；第二个结构体是一个用户的存取款记录；第三个结构体是以上述两种结构体为类型创建的两个顺序表用于存储完整的的客户信息。再实现相应功能对应的函数、系统界面、文件加载保存等等即可。
