2012年上半年项目实训“银行储蓄综合业务平台”C++版

项目名称： 银行储蓄综合业务平台
编写语言： 面向对象的C++语言

--先建一个空项目
--添加一个头文件名为“Record.h”
代码为：

#ifndef HEADER_RECORD    //#是预处理命令
#define HEADER_RECORD
#include <string>
using namespace std;

class Record
{
private:
int number;
string userName;
string passWord;
double balance;
int flag;
public:
Record();

void set_number(int number);
void set_userName(string userName);
void set_passWord(string passWord);
void set_balance(double balance);
void set_flag(int flag);

int get_number();
string get_userName();
string get_passWord();
double get_balance();
int get_flag();

void display_Record();
};
#endif

--再添加一个源文件“Record.cpp”
代码为：

#include "Record.h"
#include <iostream>
using namespace std;

Record:: Record()
{
this->number = 0;
this->userName = "";
this->passWord = "";
this->balance = 0;
this->flag = -1;
}

void Record::set_number(int number)
{
this ->number = number;
}

void Record::set_userName(string userName)
{
this ->userName = userName;
}

void Record::set_passWord(string passWord)
{
this ->passWord = passWord;
}

void Record::set_balance(double balance)
{
this ->balance = balance;
}

void Record::set_flag(int flag)
{
this ->flag = flag;
}

int Record::get_number()
{
return this -> number;
}

string Record::get_userName()
{
return this->userName;
}

string Record::get_passWord()
{
return this -> passWord;
}

double Record::get_balance()
{
return this->balance;
}

int Record::get_flag()
{
return this -> flag;
}

void Record::display_Record()
{
cout << "+-----------------------------------------------------+" << endl;
cout << "+  帐号  |  用户名     |  密码     |    余额     |  状态 +" << endl;
cout << "+-----------------------------------------------------+" << endl;
cout << "+  " << this->get_number() << " |  " << this->get_userName() << "     |  "
<< "    " << this->get_passWord() << "  |      " << this->get_balance() << "    |  ";
if(this->get_flag() == 1)
{
cout <<  "正常" ;
}
else
{
cout << "异常" ;
}
cout << " +" << endl;
cout << "+-----------------------------------------------------+" << endl;
}

---为了验证一下 Record 是否有错误，建一个源文件名为“TestRecord”
代码为：
#include "Record.h"

int main()
{
Record * record = new Record();
record->display_Record();

record->set_number(10001);
record->set_userName("zhangsan");
record->set_passWord("1023");
record->set_balance(56);
record->set_flag(1);
record->display_Record();

return 0;
}

***//用Record显示基本账户信息

--再建一个头文件名为“Node.h”
代码为：

#ifndef HEADER_NODE
#define HEADER_NODE
#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();
};
#endif

--再建一个源文件名为“Node.cpp”
代码为：

#include "Node.h"
#include <iostream>
using namespace std;

Node::Node()
{
this->record = NULL;
this->next = NULL;
}

Node::~Node()
{
delete this->record;
this->record = NULL;

}

void Node::set_record(Record * record)
{

{

{
return this->record;

{
cout << "Print Node elements..." << endl;
//cout << "Record: " << this->record <<endl;

}
else
{
Record * r = this->record;
r->display_Record();
}
cout << "Next: " << this->next << endl;
cout << "End of Node..." << endl;
cout << endl;
}

---为了验证一下Node可不可以运行，建立一个源文件名为“TestNode.cpp”
代码为：

#include "Node.h"
#include <iostream>
using namespace std;

int main()
{
Node * node = new Node();
node->display_Node();

r->set_balance(10000);
r->set_flag(1);

node->set_record(r);
node->display_Node();

return 0;
