C++ 简易 Simple_ATM_drawmoney

才学c++，昨晚突发奇想，做了一了Simple_ATM_drawmoney，后续功能持续开发中

,代码如下

//Bank.h

Bank的声明

#include<string> using namespace std; #ifndef Bank_h #define Bank_h class Bank { protected:  string Bankid;//银行卡号  int Bankpassword;//密码  int drawmoney;//要取的钱  int savemoney;//要存入的钱  int totalmoney;//总共的钱 public:  Bank();  ~Bank();      void setBankid(string);//输入账号  string getBankid()const;//获取账号  void setBankpassword(int);//输入密码  int getBankpassword()const;//获取密码  int getdrawmoney()const;//取钱   void setdrawmoney(int);//输入取钱  int getpaymoney()const;//存钱  void setpaymoney(int);//输入存钱  int gettotalmoney()const;//总钱  void print()const;//输出 }; #endif 

//Bank.cpp

//Bank的实现

#include<string>

#include<iostream> //#include<stdexcept> #include"Bank.h" using namespace std; int total=1000; Bank::Bank() ://构造函数初始化 Bankid(""), Bankpassword(-1), drawmoney(0), savemoney(0), totalmoney(1000) {} Bank::~Bank()//析构函数 {} void Bank::setBankid(string id)//设置账号 {  Bankid = id; } string Bank::getBankid()const//返回账号 {  return Bankid; } void Bank::setBankpassword(int password)//设置密码 {  Bankpassword = password; } int Bank::getBankpassword()const//返回密码 {  return Bankpassword; } void Bank::setpaymoney(int money)//要存的钱 {  savemoney = money; } int Bank::getpaymoney()const//存钱  {   total = total + savemoney;  return total; } void Bank::setdrawmoney(int money)//要取的钱 {  drawmoney = money; } int Bank::getdrawmoney()const//取钱 {  if (total < drawmoney)  {  cout << "余额不足" << endl;  return 0;  }  else  total = total - drawmoney;  return total;  //throw exception(); } int Bank::gettotalmoney()const {  return total ; } void Bank::print()const {  cout << "余额剩余" << gettotalmoney() << endl; }

//主函数 #include<iostream> #include<Windows.h> #include"Bank.h" #include<string> using namespace std; int  Print();//打印主界面 void printpaymoney(Bank *b);//存钱界面 void printdrawmoney(Bank *b);//取钱界面 int main() {  Bank *p = new Bank;  cout << "请输入银行卡号" << endl;  string id;  cin >> id;  p->setBankid(id);  //cout << p->getBankid()<< endl;  cout << "请输入密码" << endl;  int password;  cin >> password;  p->setBankpassword(password);  cout << "输入正确，正在进入主界面。。。。" << endl;  Sleep(500);  bool done = true;  while (done)  {  int section = Print();  switch (section)  {  case 1:  p->print();  break;  case 2:  printpaymoney(p);  cout << "存钱成功！您当前余额为";  cout << p->getpaymoney() << endl;  break;  case 3:  printdrawmoney(p);  cout << "您当前余额";  cout << p->getdrawmoney()<< endl;  break;  case 0:  done = false;  break;  default:  cout << "unkown command!" << endl;  }  }  return 0; } int Print() {  int section;   cout << "1)查询当前余额 " << endl;  cout << "2)存钱" << endl;   cout << "3)取钱" << endl;   cout << "0)退出" << endl;  cin >> section;  return section; } void printdrawmoney(Bank *b)//取钱界面 {  cout << "请输入您要取钱的金额" << endl;  int money;  cin >> money;  b->setdrawmoney(money); } void printpaymoney(Bank *b)//存钱界面 {  cout << "请输入您要存入的金额" << endl;  int money;  cin >> money;  b->setpaymoney(money); }
