while循環不會循環，程序在最後一個printf語句結束......任何想法爲什麼？

Question

while(play == 'y' || play == 'Y') 
{ 
      do 
      { 
        printf("Max number of guesses is %d\n", count); 
        printf("What is your guess? It must be between 1 and %d\n", $ 
        scanf("%d", &guess); 

        if(guess > randNum) 
        { 
          printf("Too large!\n"); 
          count = count -1; 
        } 
        else if(guess < randNum) 
        { 
          printf("Too small!\n"); 
          count = count -1; 
        } 
        else 
        { 
          printf("%s, you guessed my number!\n", name); 
          yourNum = guess; 
        } 
      } while(yourNum != guess || count == 0); 

      printf("Play again? (y/n)\n"); 
      scanf("%c", &play);

我覺得你需要'儘管'爲第一while while循環，以便用戶將能夠播放一次。我的假設是戲劇變量不用'Y'或'Y'初始化，這就是爲什麼while循環沒有得到執行。更多的代碼是必需的。我的建議會像this`

  do{ 
do 
      { 
        printf("Max number of guesses is %d\n", count); 
        printf("What is your guess? It must be between 1 and %d\n", $ 
        scanf("%d", &guess); 

        if(guess > randNum) 
        { 
          printf("Too large!\n"); 
          count = count -1; 
        } 
        else if(guess < randNum) 
        { 
          printf("Too small!\n"); 
          count = count -1; 
        } 
        else 
        { 
          printf("%s, you guessed my number!\n", name); 
          yourNum = guess; 
        } 
      } while(yourNum != guess || count == 0); 

      printf("Play again? (y/n)\n"); 
      scanf("%c", &play); 
}while(play == 'y' || play == 'Y')
