Question

我正在尝试开发一个程序来预订酒店房间并收取费用，但我想为人们增加一种在看到价格后拒绝房间的方式。

我尝试了一下，似乎无法找到一个答案，一旦超过接受房费的人，该如何继续下去。

#include <iostream>

using namespace std;

int main()
{

    int number_of_rooms{ 0 };
    cout << "Welcome to Trey's hotel! How many rooms can we book you for? ";
    cin >> number_of_rooms;
    cout << "Ok, we will book " << number_of_rooms << " room(s) for you!" << endl;

    double price_of_room{ 125.5 };
    char decision;
    bool run = true;
    while (run)
    {
        cout << "Each room will be " << price_of_room << " per room. Is that Ok with you? ";
        cin >> decision;
        if (decision == 'N' || decision == 'n' || decision == 'No' || decision == 'no')
            cout << "Alright, have a good day! " << endl;
        {
            run = false;
        }

        if (decision == 'Y' || decision == 'y' || decision == 'Yes' || decision == 'yes')

        {
            run = true;
        }       

    }

    cout << "Ok for " << number_of_rooms << " that will cost you ";




    return 0;
}

连续三天的编码非常不错！我可以看到两个主要问题：

您需要将cout << "Alright, have a good day!" << endl;移到其下方的括号中，以便代码显示为：

if (decision == 'N' || decision == 'n' || decision == 'No' || decision == 'no')
{
   cout << "Alright, have a good day! " << endl;
   run = false;
}

此外，您的decision声明中有错误。在您的if语句中，您检查决策是否等于“是”，但是，决策是一个字符。为确保if语句正确，您需要在文件顶部添加#include <string>，然后说string decision;。

c ++是或否问题
