如何在控制台中计算用户答案

Question

使用 C# 的第一天已经卡住了。我的问题是如何计算用户给出的所有答案以找出随机数是什么？然后用正确的答案把它放在最后一句。这就是“测验”的样子：

public static void Main(string[] args)
    {
        Console.WriteLine("The secret number\n");

        Random randomerare = new Random();
        int slump_tal = randomerare.Next(1, 101);

        Console.WriteLine("Write your number and we'll see where it lands:\n");
            string user_nr = Console.ReadLine();
            int tal = Convert.ToInt32(user_nr);
            Console.WriteLine();

            while (tal > slump_tal)
        {
                Console.WriteLine("Wrong! Your number is too big!\n");
                user_nr = Console.ReadLine();
                tal = Convert.ToInt32(user_nr);
        }
            while (tal < slump_tal)

        {
            Console.WriteLine("Wrong Your number is too low!\n");
                user_nr = Console.ReadLine();
                tal = Convert.ToInt32(user_nr);
        }

            while (tal == slump_tal)
            {
        Console.WriteLine("Bravo! That's the correct number\n");
            break;
            }

        Console.WriteLine("The secret number was: {0}\n\nPush the button to finish", slump_tal);

        Console.ReadKey(true);
    }

Answer 1

您的代码中有两个步骤。你把它们弄混了。

第 1 步：执行 while 循环以不断获取用户的输入。

第 2 步：在每个循环中，您需要根据数字验证输入。

它应该是 1 个大的 while() 循环和 3 个 if ()。如果您需要示例代码，请告诉我。

Answer 2

我会这样做：

 1. Get a number
 2. While the user is not hitting the right number:
      2.1 let the user know if the number was too big or too small
      2.2 ask for another number
      2.3 count number-of-attems + 1
 3. If the user arrived here, it means it has the number right, print number-of-attems

在代码中，这可能如下所示：

    public static void Main(string[] args)
    {
        Console.WriteLine("The secret number\n");

        Random randomerare = new Random();
        int slump_tal = randomerare.Next(1, 101);

        Console.WriteLine("Write your number and we'll see where it lands:\n");
        Console.WriteLine();


        int user_nr = Convert.ToInt32(Console.ReadLine());

        // Here you can store the attempts
        int attempts = 1;

        // While the user provides the wrong answer, we iterate
        while(slump_tal != user_nr)
        {

            // We add 1 to the counter
            attempts++;

            if (slump_tal > slump_tal)
            {
                Console.WriteLine("Wrong Your number is too low!\n");
            }
            else 
            {
                Console.WriteLine("Wrong! Your number is too big!\n");
            }

            user_nr = Convert.ToInt32(Console.ReadLine());
        }

        Console.WriteLine($"Bravo! That's the correct number. you did it in {attempts} attemps");
        Console.WriteLine("The secret number was: {0}\n\nPush the button to finish", slump_tal);
        Console.ReadKey(true);
    }
