Question

我正在制作一个随机数猜测游戏，计算机认为是1-100之间的数字。然后它会询问你它是什么，并告诉你你是对还是错。但是，每当我调试时，由于某种原因它会说它高于或低于实际随机数。此外，它同时说出其中两个陈述。另外，我不知道怎么说这个人已经猜了多少次。这是我不成功的代码。

static void Main(string[] args) 
{
    Random random = new Random();

    int returnValue = random.Next(1, 100);
    int Guess = 0;

    Console.WriteLine("I am thinking of a number between 1-100.  Can you guess what it is?");

    while (Guess != returnValue)
    {
        Guess = Convert.ToInt32(Console.Read());

        while (Guess < returnValue)
        {
            Console.WriteLine("No, the number I am thinking of is higher than " + Guess + " .  Can you guess what it is?");
            Console.ReadLine();

        }
        while (Guess > returnValue)
        {
            Console.WriteLine("No, the number I am thinking of is lower than " + Guess + " .  Can you guess what it is");
            Console.ReadLine();
        }
    }
    while (Guess == returnValue)
    {
        Console.WriteLine("Well done! The answer was " + returnValue);
        Console.ReadLine();
    }
}

Answer 1

您正在使用不需要的迭代的批次。 while语句采用布尔条件，就像IF语句一样。

static void Main(string[] args)

{

Random random = new Random();

int returnValue = random.Next(1, 100);

        int Guess = 0;

        Console.WriteLine("I am thinking of a number between 1-100.  Can you guess what it is?");

        while (Guess != returnValue)
        {
            Guess = Convert.ToInt32(Console.Read());

            if (Guess < returnValue)
            {
                Console.WriteLine("No, the number I am thinking of is higher than " + Guess + ". Can you guess what it is?");
            }
            else if (Guess > returnValue)
            {
                Console.WriteLine("No, the number I am thinking of is lower than " + Guess + ". Can you guess what it is?");
            }

        }

        Console.WriteLine("Well done! The answer was " + returnValue);
        Console.ReadLine();

}

Answer 2

尝试重构逻辑，使其完全符合您的要求。

Random r = new Random();

int val = r.Next(1, 100);
int guess = 0;
bool correct = false;

Console.WriteLine("I'm thinking of a number between 1 and 100.");

while (!correct)
{
    Console.Write("Guess: ");
    string input = Console.ReadLine();

    if (!int.TryParse(input, out guess))
    {
        Console.WriteLine("That's not a number.");
        continue;
    }

    if (guess < val)
    {
        Console.WriteLine("No, the number I'm thinking is higher than that number.");
    }
    else if (guess > val)
    {
        Console.WriteLine("No, the number I'm thinking is lower than that number.");
    }
    else
    {
        correct = true;
        Console.WriteLine("You guessed right!");
    }
}

Answer 3

尝试改为while s if。如：

if (Guess < returnValue)
{
   Console.WriteLine("No, the number I am thinking of is higher than " + Guess + " .  Can you guess what it is?");
}
if (Guess > returnValue)
{
   Console.WriteLine("No, the number I am thinking of is lower than " + Guess + " .  Can you guess what it is");
}

您也可能想要输入：

Console.WriteLine("I am thinking of a number between 1-100.  Can you guess what it is?");

提示在while循环内部，以便在每次提示之前不断询问您。

Answer 4

您需要将While循环更改为if-then-else语句

只要语句为真，

会运行其代码。所以，在你的代码中，你运行第一个 - 基本上是永远的，因为你没有重置你的条件中的任何一个值。

如果你的while循环WERE要退出，那么你的while循环就会遇到同样的问题。你想要这样的东西：

if ( guess > myValue ) { // do something }
else ( guess < myValue ) {//do something else}
else { // do a third thing }

Answer 5

正如其他人所说，你误导了while，其中if确实是必要的。

static void Main(string[] args) 
{

    Random random = new Random();

    int returnValue = random.Next(1, 100);
    int Guess = 0;
    int numGuesses = 0;

    Console.WriteLine("I am thinking of a number between 1-100.  Can you guess what it is?");

    while (Guess != returnValue)
    {
        Guess = Convert.ToInt32(Console.Read());
        string line = Console.ReadLine(); // Get string from user
        if (!int.TryParse(line, out Guess)) // Try to parse the string as an integer
            Console.WriteLine("Not an integer!");
        else {
            numGuesses++;
            if (Guess < returnValue)
            {
                Console.WriteLine("No, the number I am thinking of is higher than " + Guess + " .  Can you guess what it is?");
            }
            if (Guess > returnValue)
            {
                Console.WriteLine("No, the number I am thinking of is lower than " + Guess + " .  Can you guess what it is");
            }
        }
    }
    Console.WriteLine("Well done! The answer was " + returnValue + ".\nYou took " + numGuesses + " guesses.");
}

...哥们

    int total = 1,
            low = 0,
            high = 0;
        int ranNum1,
            guess;

        string guessStr;

        Random ranNumGen = new Random();
        ranNum1 = ranNumGen.Next(1, 10);

        Console.Write("Enter your guess >> ");
        guessStr = Console.ReadLine();
        guess = Convert.ToInt16(guessStr);

        while (guess != ranNum1 )
        {
            while (guess < ranNum1)
            {
                Console.WriteLine("Your guess is to low, try again.");
                Console.Write("\nEnter your guess >> ");
                guessStr = Console.ReadLine();
                guess = Convert.ToInt16(guessStr);
                ++total;
                ++low;
            }
            while (guess > ranNum1)
            {
                Console.WriteLine("Your guess is to high, try again.");
                Console.Write("\nEnter your guess >> ");
                guessStr = Console.ReadLine();
                guess = Convert.ToInt16(guessStr);
                ++total;
                ++high;
            }
        }
        //total = low + high;
        Console.WriteLine("It took you {0} guesses to correctly guess {1}", total, ranNum1);

生成1到9之间的随机数（包括1和9）。向用户询问用户是否获得该号码，然后告诉他们他们是否猜到了太低或太高，或者说是正确的。续语：让游戏继续进行，直到用户输入“退出”跟踪用户已经采取了多少猜测，当游戏结束时，打印出来。

Answer 8

你好，也许这对你没问题，但对于其他想尝试的人：

using System;

namespace Exemple
{
    class Program
    {
        static void Main(string[] args)
        {
            Random random = new Random();
            int returnvalue = random.Next(1, 51);

            Console.WriteLine(" Guess a number between 1 to 51 ");
            int response = Convert.ToInt32(Console.ReadLine());

            while (response > returnvalue)
            {
                Console.WriteLine($"No the number is low than {response} try again !");
                response = Convert.ToInt32(Console.ReadLine());
            }

            while (response < returnvalue)
            {
                Console.WriteLine($"No the number is high than {response} try again !");
                response = Convert.ToInt32(Console.ReadLine());
            }

            while (response != returnvalue)
            {
                Console.WriteLine($" wrong answer {response} is not the good response try again !");
                response = Convert.ToInt32(Console.ReadLine());
            }

            Console.WriteLine($"Good ! Its  {returnvalue}");

        }
    }
}
