平铺快速项目

Question

所以我是C ++的新手。我正在学习基础知识，并且我一直在尝试编译这个程序。不幸的是，每当我运行它时，瓷砖的价格当然非常低，并且瓷砖的数量也不会以合理的方式返回。请帮忙！

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


int main()
{
    double cost_tile, side_tile_in, width_room, lenght_room;
    cout << "How much is one tile? \n";
    cin >> cost_tile;

    cout << "What is the length of one side of a tile in inches? \n";
    cin >> side_tile_in;

    double side_tile_ft, tile_area_ft;
    side_tile_ft = side_tile_in * 12;
    tile_area_ft = side_tile_ft * side_tile_ft;

    cout << "What is the width of the room in feet? \n";
    cin >> width_room;
    cout << "What is the length of the room in feet? \n";
    cin >> lenght_room;

    double area_room, tiles;
    area_room = width_room * lenght_room;
    tiles = area_room/tile_area_ft;

    cout << "You will cover an area of " << area_room << " square feet, with " << tiles << "tiles \n";
    cout << "The cost for the tiles will be $" << cost_tile *  tiles;
    return 0;
}

要将英寸转换为英尺，除以12，而不是乘以12。
