Question

这是我遇到问题的代码，我试图检索错误猜测数量的值（numbWrong）。为什么我无法检索错误猜测的数量？

...
{
    Console.WriteLine("Enter your guess letter using lowercase only.");
    char input = Console.ReadLine().ToCharArray()[0];

    for (int i = 0; i < myWord.Length; i++)
    {
        //if the user guessed right, replace the correct dash and display to the user
        if (myWord[i] == input)
        {
            count++; //update the count
            a[i] = input;  //if guess is correct, dash is replaced by what the user used as input

            //show the new dash array mixed with correct guesses
            for (int j = 0; j < a.Length; j++)
            {
                Console.Write(a[j] + " ");
            }
            else
            {
                numbWrong += 1;
            }
        }

        Console.WriteLine();
        Console.WriteLine("You guessed it right after ");
        Console.Write(numbWrong);
        Console.Write(" incorrect guesses.");
    }

错误：

"Use of unassigned local variable 'numbWrong' "

Answer 1

您的变量未初始化。将其从循环中取出并将其放在代码中，如下所示。希望有所帮助。编辑：prescot先得到它。但是答案相同。

int numbWrong = 0; //change
for (int i = 0; i < myWord.Length; i++)
{
    //if the user guessed right, replace the correct dash and display to the user
    if (myWord[i] == input)
    {
        count++; //update the count
        a[i] = input;  //if guess is correct, dash is replaced by what the user used as input

        //show the new dash array mixed with correct guesses
        for (int j = 0; j < a.Length; j++)
        {
            Console.Write(a[j] + " ");
        }
    }
    else
    {
        numbWrong += 1;
    }
}

Answer 2

您在哪里定义numbWrong？在for循环之前，您应该声明numbWrong：

int numbWrong = 0;

这应该可以帮助你，你没有初始化你的变量，一旦初始化你的计算错误猜测的方法是错误的，这是因为你在每个字符的每次迭代中计算它，当它应该被计算一次每次迭代都在一个单词上。
