C++：模拟银行储蓄系统

1、设计并实现一个简单的银行储蓄系统，完成活期和定期用户的存款和取款业务。

2、实现描述银行的类，记录系统中现有哪些储户（提示：可用对象数组实现，但须注意判断数组越界的情况），该类中要求包含三个函数：（1）生成新储户的函数；（2）按照账户删除储户的函数；（3）按照账户查询储户的函数，要求显示查询结果。

3、定义储户类。其属性包含账号，存款人姓名、身份证号、地址、存款余额；其操作有存款、取款、显示储户信息。

4、编写main()函数，测试上述所要求的各项功能。

#include <iostream>
#include <string>
#include<string.h>
using namespace std;
//定义储户类。其属性包含账号，存款人姓名、身份证号、地址、存款余额；其操作有存款、取款、显示储户信息。
class Account
{
private:string Account_name;//账号string pwd;string name;//存款人姓名double balance ;//余额char ID[19];string adress;
public:Account(string a,string p,string b,double bal,char id[18],string ad){Account_name = a;//用户账号pwd=p;//密码name = b;//姓名balance = bal;//余额ID[19]=id[19];//身份证号adress=ad;//地址}//存款virtual void saving(double a);//取款virtual void withdrow(double a);//显示账户信息virtual void showme();string getId(){return Account_name;}
};
void Account::saving(double a){balance = balance + a;cout<<"已存入"<<a<<"元"<<endl;
}
void Account::withdrow(double a){if(a > balance)cout<<"余额不足"<<endl;else{balance = balance - a;cout << "已取出" << a << "元" <<endl;}
}
void Account::showme(){cout << "用户账号为" << Account_name << endl;cout << "用户密码为" << pwd << endl;cout << "开户人姓名" << name <<endl;cout << "账户余额为" << balance <<"元"<<endl;
}
//定义活期储户类
class CurrentAccount:public Account
{
private:string Account_name;//账号string pwd;string name;//存款人姓名double balance ;//余额char ID[19];string adress;
public:CurrentAccount(string a,string p,string b,double bal,char id[18],string ad):Account(a,p,b,bal,id,ad){}
};
//定义定期储户类
class RegularAccount:public Account
{
private:string Account_name;//账号string pwd;string name;//存款人姓名double balance ;//余额char ID[19];string adress;string deposit_time;//存款时间string withdrawal_time;//取款时间
public:RegularAccount(string a,string p,string b,double bal,char id[18],string ad,string depo,string with):Account(a,p,b,bal,id,ad){Account_name = a;//用户账号pwd=p;name = b;//姓名balance = bal;//余额ID[19]=id[19];//身份证号adress=ad;//地址deposit_time=depo;withdrawal_time=with;}void showme(){cout << "用户账号为" << Account_name << endl;cout << "用户密码为" << pwd << endl;cout << "开户人姓名" << name <<endl;cout << "账户余额为" << balance <<"元"<<endl;cout<<"定期存储存款时间为："<<deposit_time<<endl<<"定期存储取款时间为："<<withdrawal_time<<endl;}
};
//实现描述银行的类，记录系统中现有哪些储户（提示：可用对象数组实现，但须注意判断数组越界的情况），
//该类中要求包含三个函数：（1）生成新储户的函数；（2）按照账户删除储户的函数；
