C代码，随机骰子游戏所需的帮助未给出正确答案

Question

我正在尝试制作一个随机分配3个骰子骰子的游戏，显示3个骰子的第一个总和，然后询问用户他们是否认为下一骰子的总和将更高（h），更低（l）或相同（ S）。 我觉得我已经接近要运行它了，但是当我运行游戏时，我似乎无法获得用户输入，使它与答案应该是“对等的”（如果这样的话。）。

到目前为止，这是我的代码：

 #include<stdio.h>
 #include<stdlib.h>
 #include<ctype.h>
 #include<string.h>
 #include<math.h>
 #include<time.h>

 int main(){

   srand(time(NULL));
   char userInput;
   int diceOne=(rand()%6)+1;
   int diceTwo=(rand()%6)+1;
   int diceThree=(rand()%6)+1;
   int firstRoll = diceOne+diceTwo+diceThree;
   int prevSum,newSum;

   printf("***Welcome to the dice guessing game!***\n\n");
   printf("Rules:\n type 'quit' to exit game\n'h' for higher\n'l' for lower\n's' for same.\n\n"); 
   printf("dice one: %d\ndice two: %d\ndice three: %d\n",diceOne, diceTwo, diceThree);
   printf("The starting total is: %d\n",firstRoll);

   while(&userInput!="quit" ){

     void randDice (void){
       diceOne=(rand()%6)+1;
       diceTwo=(rand()%6)+1;
       diceThree=(rand()%6)+1;
     }

     printf("Guess:");
     scanf("%c\n\n",&userInput);

     prevSum = diceOne+diceTwo+diceThree;
     randDice();
     newSum = diceOne+diceTwo+diceThree;

     if((userInput=='h') && (prevSum > newSum)){
     printf("Correct!\n");
     printf("The sum of the three dice was: %d \n\n", prevSum);
   } else if((userInput=='l') && (prevSum < newSum)){
     printf("Correct!\n");
     printf("The sum of the three dice was: %d \n\n", prevSum);
   } else if((userInput=='s') && (prevSum == newSum)){
     printf("Correct!\n");
     printf("The sum of the three dice was: %d \n\n", prevSum);
   } else {
     printf("Incorrect\n");
     printf("The sum of the three dice was: %d \n\n", prevSum);
   }
 } 
 return 0;

}

运行此代码的输出如下：

***Welcome to the dice guessing game!***

Rules:
 type 'quit' to exit game
'h' for higher
'l' for lower
's' for same.

dice one: 3
dice two: 4
dice three: 1
The starting total is: 8
Guess:h
h
Incorrect
The sum of the three dice was: 8

Guess:h
Incorrect
The sum of the three dice was: 8

Guess:h
Correct!
The sum of the three dice was: 9

Guess:l
Incorrect
The sum of the three dice was: 4

如您所愿，我必须在游戏继续运行之前的第一次输入两个输入。 在输出示例中，当骰子的总和从8变为9时，我猜了几次h（high）并使其一次正确，但是当我输入l（lower）并且骰子从9变为4时，我得到“不正确”。

  while(&userInput!="quit" ){

您正在读取函数中的单个字符，这意味着这将永远不等于true。

  scanf("%c\n\n",&userInput);

改用fgets ，然后用sscanf将其读入char
