C++版酒店管理程序代码

程序代码N：最终改进版代码（利用结构体储存多种类型的数据）好处：比数组能储存更多类型的数据！#include<iostream>#include<string>#include<cstdlib> //常用函数库using namespace std;/*在c++中struct和类的区别在于struct不能有方法，所有成员是public的*/struct Room{int Number;int Price;int State;int days;string Name;string Phone;string ID;};//room; 可以在声明struct的时候声明一个struct实例Room room[80];class BookRoom //定义预定房间类{private:string cName; //顾客姓名int stayTime; //预定天数int roomType; //房间类型（1.标准单人间2.大床房3.标准双人间4. 套房）string phoneNum; // 预留手机号public:void setData(){string name;int time;int type;string num;cout<<"您好，请输入您的姓名："<<endl;cin>>name;
