Question

我想要求用户输入最多20个房屋的详细信息。我需要按用户输入的房屋数量重复我的问题。
然后我想在列表中显示详细信息

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

class House
{
      private :
             int NumRooms;
             int Area;
             int FloorNumber;
      public :

             void Getdata()
             {
                   cout << "Enter number of rooms in house: ";
                   cin >> NumRooms;
                   cout << "Enter area of house: ";
                   cin >> Area;
                   cout << "Enter floor number of house: ";
                   cin >> FloorNumber;
             }
             void Putdata()
             {
                   cout  << "Number of rooms: " << NumRooms << endl;
                   cout << "Area of house: " << Area << endl;
                   cout << "Floor number: " << FloorNumber << endl;
            }
};

int _tmain(int argc, _TCHAR* argv[])
{
    House s;
    s.Getdata();
    s.Putdata();
    system("pause");
    return 0;
}

Answer 1

#include <vector>

int _tmain(int argc, _TCHAR* argv[])
{
    cout << "Enter number of house you want to enter: ";
    int nhouses;
    cin >> nhouses;

    std::vector<House> houses;

    for (int i=0; i<nhouses; i++) {
        House s;
        s.Getdata();
        houses.push_back(s);
    }

    for (auto& hit = houses.begin(); hit != houses.end(); ++hit)
        hit->PutData();

    system("pause");
    return 0;
}

这实际上支持任意数量的房屋（超过20个）。如果你真的想将数字限制为20只需插入一个

if (nhouses > 20) {
    std::cout << "more than 20? you are a horrible person" << std::endl;
    return -1;
}

Answer 2

我是c ++的新手，但是通过查看你的问题看起来有点模糊，但无论如何我都会去看看

1）如何将房子声明为数组房子[30];

    and taking the inputs inside a for loop??? or a do-while

怎么重复这堂课？
