随机数猜谜游戏

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，它同时说出了其中两个陈述。 另外，我不知道怎么说这个人有多少猜测。 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 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

你正在使用大量不必要的迭代。 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(); }

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

if是s，请尝试制作while s。 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：

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

在while循环中提示while以便在每次提示之前不断询问你。

Answer 4

你需要将While循环更改为if-then-else语句

只要语句为真，一段时间就会运行它的代码。 所以，在你的代码中，你运行第一个 – 基本上是永远的，因为你没有重置条件中的任何一个值。

如果你的while循环WERE要退出，那么你在while循环中遇到同样的问题。 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，你是在滥用， while if真的需要的话。

 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."); }

多德…

  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）。 让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太低或太高，或者说是完全正确。 附加function：保持游戏继续进行，直到用户输入’退出’跟踪用户已经进行了多少猜测，并且当游戏结束时，打印出来。
