按下任意键而不按下回车键退出“do while”？

Question

遇到我的代码无法正常工作的问题。我试图通过按下键盘上的任意键，但不按回车键来退出该操作。我的代码片段如下。

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(); 
}

我想你可以使用名为“kbhit”的函数，它位于“conio.h”头文件中。详情请点击this。你可以这样修改：

while(!kbhit());
