当循环无限长时

Question

我希望代码继续运行，直到用户猜出正确答案。 然而，代码无限地运行其他东西。

public class Quiz{
    //Make various questions with correct/incorrect options
    /*
    * Suggestion
    * Question 1
    * How old was the first king of sweden when he passed?
    * Options1
    * 40
    * 60
    * 80
    */
    public static int correctAnswer = 40;
    public static int guess = Convert.ToInt32(Console.ReadLine());

    public static void Guess(){
        System.Console.WriteLine("How old was the 1st King of Sweden\n");
        System.Console.WriteLine("when he passed away?");
     while(guess != correctAnswer){
        if(guess == correctAnswer){
            System.Console.WriteLine("Correct answer. Congratulations.");
        } else{
            System.Console.WriteLine("Try again.");
        }
     }
    }
}

我尝试将 do-while 更改为 while，但这没有帮助。

Answer 1

在第一次设置后，你永远不会给

guess

分配任何东西。您需要在每次迭代中重新分配

guess

：

public static int correctAnswer = 40;
public static int guess;

public static void Guess()
{
    System.Console.WriteLine("How old was the 1st King of Sweden\n");
    System.Console.WriteLine("when he passed away?");
    guess = Convert.ToInt32(Console.ReadLine());
    while(guess != correctAnswer)
    {
        System.Console.WriteLine("Try again.");
        guess = Convert.ToInt32(Console.ReadLine());
    }
}
