Question

我需要做一个Guessing游戏，程序生成一个随机数，用户必须猜测数字。如果用户在少于10次猜测中猜测该数字，该程序会祝贺他们并让他们知道他们在10次猜测之下。如果他们超过10个猜测，那么它会让他们知道它高于10等等。

我面临的问题是，例如，如果用户猜测3次尝试中的数字，然后决定再次使用一个全新的其他数字，这次猜测它是8次尝试，而不是仍然祝贺他们因为它不到10次尝试，它计算前一场比赛的3次尝试。然后，这导致程序告诉他们他们超过10次尝试，即使他们不是。我不知道如何解决这个问题。我到目前为止所做的代码如下：

int main()
{
   srand(time(0));
   int guess;
   int number;
   char selection = 'y';
   int numberOfGuesses=0;

 while(selection == 'y' || selection == 'Y')
 {
      number = rand() % 1000 + 1;

      cout << "I have a number between 1 and 1000.\nCan you guess my number?\nPlease type your first guess: ";
      cin >>guess;

      do
      {
         if(number > guess)
         {
            cout << "Too low. Try again: " << endl;
            cin >> guess;
            numberOfGuesses++;
         }
         if (number < guess)
         {
            cout << "Too high. Try again: " << endl;
            cin >> guess;
            numberOfGuesses++;
         }

      } 

      while(number != guess);

      if(numberOfGuesses < 9)
      {
            cout << "You guessed the number in less than 10 guesses!\n Would you like to play again (y or n)?";
            cin >> selection;
      }
      else if(numberOfGuesses > 9)
      {
            cout << "You guessed the number\n Would you like to play again (y or n)?";
            cin >> selection;
      }

      else if(numberOfGuesses == 9)
      {
            cout << "You guessed the number.\n Would you like to play again (y or n)?";
            cin >> selection;
      }

  }

   return 0;
 }

Answer 1

问题是您没有重置计数器。只需将int numberOfGuesses=0;放在while循环中：

while(selection == 'y' || selection == 'Y')
{
    int numberOfGuesses=0;
    ....
}

Answer 2

您需要在每场比赛前将numberOfGuesses设置为0。程序首次启动时，您的程序只会设置一次。

Answer 3

每轮结束后，您没有将numberOfGuesses重置为零。您可以使用以下几种方法之一解决问题。

在第一个numberOfGuesses循环结束时将while的值重置为零。

while(selection == 'y' || selection == 'Y')
{
   ...
   numberOfGuesses = 0;
}

在while循环开始之前，不要定义变量。将其定义为第一个语句并将其初始化为零。
```
while(selection == 'y' || selection == 'Y')
{
   int numberOfGuesses = 0;
   ...
}
```
