C++课程设计
*******************************

课题：简单银行系统模拟ATM

系别：计科系

专业年级：XXXXXX

学号：XXXXX

姓名：XXXX

一、 设计任务分析
根据课程设计要求及个人具体情况，分析如下：系统具有注册开户、用户登录、退出功能。
注册开户中有身份证号码、姓名、地址、电话号码、货币类型、预存金额。
用户登录中，用户登录成功后，才能享受取款、存款、修改密码等服务。
二、 类（对象）设计
据上得，设计类AccountItem和Accountbook。其类图如下：
AccountItem
string m_Anumber;
string m_Password;
string m_Name;
double m_Balance;
string m_Adress;
string m_ID;
string m_TEL;
string m_Currency;

AccountItem(AccountItem &a)；
AccountItem &operator=(AccountItem &a)；
AccountItem();
AccountItem(string number,string password,string name,double balance,string Currency,string TEL,string ID,string Adress);
void Display();
void write(ofstream &out);
void read(ifstream& cin);
int CheckNumber(string Anumber);
string GetNumber();
string GetPassword();
void UpdatePassword(string password);
void DeductBalance(double pay);
void StoreBalance(double money);
double GetBalance();
string GetName();
int IsNull();
Accountbook
AccountItem b[100];
int m_AccountCount;
void SetAccountbook();
Accountbook();
void LoadAccountbook();
void StoreAccountbook();
AccountItem FindItem(string number);
bool UpdateItem(AccountItem Item);

五、测试情况

1.首页：
2.注册用户：
3.用户登录：
4.取款：
5.存款：
6.查询余额：
7.修改密码：
8.退出：

六、小结
1.系统未能实现账户类型相关的系列操作、系统安全性较低，对此感到较为遗憾。
2.通过这几个周的实践，感到自己有太多的不足之处。课程设计真的是太考验和历练人了，对我来说，这是很大的挑战，虽然做的不是很好，但我相信，有我一直的努力，一定会进步的。
