用c++编写银行账户管理系统

开发银行账户管理系统, 实现增添账户, 查询账户记录（余额及历史记录），存取款后修改余额等功能。
普通用户可以进行自助查询，管理员可增删账户及存取款、转账及查询等操作。
要求将账户信息保存到文件中，从文件中读取数据；

4个头文件[cpp] #include "LinkList.h" class Bank { private: LinkList * list; int account_number; public: Bank(); ~Bank(); void set_list(LinkList *list); LinkList *get_list(); LinkList *make_list(); Record *make_record(string userName,string passWord,double balance); int creat_number(); int get_number(); string get_userName(); string get_passWord(); double get_balance(); Record *find_record(int number); void open_acount(); void close_acount();//销户 void find_acount(); void deposit();//存款 void withdraw();//取款 }; [html] #include "Node.h" class LinkList { private: Node *head; int len; public: LinkList(); ~LinkList(); void set_head(Node *head); Node *get_head();//获得头节点 int get_len(); Node *make_node(Record *record);//制作一个节点，目的是插入record void insert_node(Node *node);//插入一个节点 Node *find_node(int number);//找到一个节点，通过账户（number)查找 void display_LinkList(); };
[html] #include "Record.h" class Node { private: Record *record; Node *next; public: Node(); ~Node(); void set_record(Record *record); void set_next(Node *next); Record *get_record(); Node *get_next(); void display_Node(); };
[cpp] #include <iostream> #include <string> using namespace std; class Record { private: int number; double salary; string userName; string passWord; int flag; public: Record(); void set_number(int number); void set_salary(double salary); void set_userName(string userName); void set_passWord(string passWord); void set_flag(int flag); int get_number(); double get_salary(); string get_userName(); string get_passWord(); int get_flag(); void display(); };

追问

谢谢啦哈，好心人！！！
对了，问一下哈，您能不能给用Word文档给整理一下，看起来有点乱诶....
好心人，帮帮忙，整理好给发有邮箱里呗...邮箱jiangbaoliang123@163.com，
在此，发自内心的感谢！！！
