Question

我搜索了我的查询，但无法找到任何有用的内容。我刚开始学习Java，我制作了一个基本的猜谜游戏程序。我的问题是我需要计算用户猜测的数量，我不确定如何做到这一点。我真的很感激你们给我的任何帮助。到目前为止，这是我的代码：

double ran;
ran = Math.random();
int r = (int)(ran*100);

Scanner in = new Scanner (System.in);
int g = 0;

System.out.print("Please make a guess between 1 and 100: ");
g = in.nextInt();

while (g!=r){

  if (g<=0){
    System.out.print("Game over.");
    System.exit(0); 
  }

  else if (g>r){
    System.out.print("Too high. Please guess again: ");
    g = in.nextInt();
  }

  else if (g<r){
    System.out.print("Too low. Please guess again: ");
    g = in.nextInt();                               
  }
}

System.out.print("Correct!");

Answer 1

您需要一个变量来跟踪您的猜测次数。声明它只会在每场比赛中运行一次，而不是

int guessCount = 0

然后，在猜测循环中，增加guessCount。

guessCount++

Answer 2

有一个count变量，并在每次迭代时在while内增加。

    int count=0;
     while(g!=r) {

        count++;
        //rest of your logic goes here
        }

Answer 3

所以你想要维护一个计数器，即一个可以计算猜测次数的变量，每当你要求用户做出时，你会想要将计数增加一个一个猜测。所以基本上，每次调用g = in.nextInt();

时都应该递增计数器

所以这就是你的代码应该做的......

double ran;
ran = Math.random();
int r = (int)(ran*100);
Scanner in = new Scanner (System.in);
int g = 0;
System.out.print("Please make a guess between 1 and 100: ");
int counter = 0;
g = in.nextInt();
counter++;
while (g!=r) {
    if (g<=0) {
        System.out.print("Game over.");
        System.exit(0);
    }
    else if (g>r) {
        System.out.print("Too high. Please guess again: ");
        g = in.nextInt();
        counter++;
    }
    else if (g<r) {
        System.out.print("Too low. Please guess again: ");
        g = in.nextInt();
        counter++;
    }
}
System.out.print("Correct!");
