通过按任意键而不按回车键退出“do while”？

Question

我的代码出现问题，无法正常工作。我试图通过按键盘上的任意键但不按回车键让它退出执行。我的代码 sn-p 如下。

void LemonadeBuyANDCheck()
{
    int iCupsToBuy = rand() % (MAX_CUPS - MIN_CUPS) + MIN_CUPS;


    bool continueLoop = true;
    do 
    {
        int Userinput = 1;
        Userinput = !_kbhit();
        fflush(stdin);

        if (Userinput == 1)
        {
            continueLoop = false;
        }

        StoreIsOpen();
        int randomNumber = rand() % 100;

        if (iCupsOfLemonadeInStock == 0)
        {
            cout << "Customer came to buy some lemonade but you didnt have any in stock :(\n";
            //continueLoop = false;
        }

        else if (randomNumber <= 25)
        {

            cout << "Wow your lemonade is way too expensive!\n";
            iCustomerCounter++;

        }

        else if (randomNumber >= 75)
        {

            cout << "Eww your recipe for lemonade... Wow..\n";
            iCustomerCounter++;
        }


        else if (iCupsOfLemonadeInStock >= iCupsToBuy)
        {

            cout << "You sold " << iCupsToBuy << "cups of lemonade!\n";

            iCupsOfLemonadeInStock = iCupsOfLemonadeInStock - iCupsToBuy;
            iCupsOfLemonadeSold = iCupsOfLemonadeSold - iCupsToBuy;
            //Money

            fMoneyEarned += (iCupsToBuy * fCurrentLemonadePrice);
            fCurrentMoney += (iCupsToBuy * fCurrentLemonadePrice);

            iCustomerCounter++;
        }
        else if (iCupsOfLemonadeInStock < iCupsToBuy)
        {
            cout << "You didnt have enough lemonade in stock so you only sold " << iCupsToBuy - iCupsOfLemonadeInStock << endl;

            fMoneyEarned += (iCupsOfLemonadeInStock * fCurrentLemonadePrice);
            fCurrentMoney += (iCupsOfLemonadeInStock * fCurrentLemonadePrice);
            iCupsOfLemonadeInStock = 0;

            iCustomerCounter++;
        }
    } while (continueLoop != true);
    fflush(stdin);
        GameMenuSelectionVerifier();
}

我认为您可以使用名为“kbhit”的函数，它位于“conio.h”头文件中。详情可点击this。你可以像这样修改它：

while(!kbhit());
