二、具体内容模拟实现银行ATM自动取款机系统。

系统主要功能：（1）客户登录（2）余额查询（3）取款（4）转账（5）借存记录查询1 项目分析了解项目应用领域的ATM流程、操作规范，明确项目需求、确定项目功能。

1.1功能描述画出功能结构图，介绍系统中各模块的主要功能。

1.2 ATM流程画出系统ATM流程图。

1.3数据库设计根据系统数据需求，进行数据库概念设计、数据表设计。

用户信息表:1.4功能模块分记录查询recordidnamestates zmoney 记录查询介绍系统的功能模块设计思路，画出模块工作流程图。

2 项目实现使用C++编程实现项目。

2.1 功能模块设计系统中各类关系图，类的设计（类的定义）。

class ATM{public:int withdraw();//取款void zhuan();//转账void balance();//余额查询int interfac();//登陆int menu1();//菜单void record_info();//记录查询public:string name;//用户名string number;//账号float money;//余额string password;//密码};2.2 项目实现系统中各类的实现（各类成员函数的实现）。
