环路因条件而终止，但条件是必要的？

Question

我正在研究一个猜谜游戏。

问题是我必须将remainingguesses设置为0，这样一个人可以使得猜测的数量减少1个。但是同时循环中设置的条件是基于remainingguesses不是0。它是0循环终止并继续。

我不知道如何解决这个问题，同时使循环中的条件正常工作。

这里是有问题的循环：

printf("Type the number of guesses that player 2 gets and press return: \n"); 
    scanf("%d",&guesses); 

    remainingguesses = 0; 

    while (remainingguesses != 0) { 
    printf("Player 2: Type your guess and press return (guesses remaining:%d):\n",remainingguesses); 
    scanf(" %d",&secretnumberguess); 
    remainingguesses = guesses - 1; 

    if (secretnumberguess > secretnumber) { 
     printf("Your guess was greater than the secret number.\n"); 
    } 

    else if (secretnumberguess < secretnumber){ 
     printf("Your guess was less than the secret number.\n"); 
    } 

    else{ 
      printf("Your guess was equal to the secret number. You win!\n"); 
    } 
    } 

    if (remainingguesses == 0) 
    printf("Sorry you are out of guesses. You lose.\n"); 

如果需要，这里是有问题的全码：

#include <stdio.h> 

int main() 
{ 

    int secretnumber; 
    int guesses; 
    int secretnumberguess; 
    int remainingguesses; 

    while (1) { 
    printf("Player 1: Type a number between 0 and 99 and press return:\n"); 
    scanf(" %d",&secretnumber); 

    if (secretnumber > 99 || secretnumber < 0) { 
     printf("Secret number cannot be greater than 99 or below 0.\n"); 
     continue; 
    } 
    break; 
    } 

    printf("Type the number of guesses that player 2 gets and press return: \n"); 
    scanf("%d",&guesses); 

    remainingguesses = 0; 

    while (remainingguesses != 0) { 
    printf("Player 2: Type your guess and press return (guesses remaining:%d):\n",remainingguesses); 
    scanf(" %d",&secretnumberguess); 
    remainingguesses = guesses - 1; 

    if (secretnumberguess > secretnumber) { 
     printf("Your guess was greater than the secret number.\n"); 
    } 

    else if (secretnumberguess < secretnumber){ 
     printf("Your guess was less than the secret number.\n"); 
    } 

    else{ 
      printf("Your guess was equal to the secret number. You win!\n"); 
    } 
    } 

    if (remainingguesses == 0) 
    printf("Sorry you are out of guesses. You lose.\n"); 

    return 0;

简化代码：

#include <stdio.h> 

int main() 
{ 

    int secretnumber; 
    int guesses; 
    int secretnumberguess; 
    int flag=0; 

    while (1) { 
    printf("Player 1: Type a number between 0 and 99 and press return:\n"); 
    scanf(" %d",&secretnumber); 

    if (secretnumber > 99 || secretnumber < 0) { 
     printf("Secret number cannot be greater than 99 or below 0.\n"); 
     continue; 
    } 
    break; 
    } 

    printf("Type the number of guesses that player 2 gets and press return: \n"); 
    scanf("%d",&guesses); 


    while (guesses > 0 && flag==0) { 
    printf("Player 2: Type your guess and press return (guesses remaining:%d):\n",guesses); 
    scanf(" %d",&secretnumberguess); 
    guesses=guesses - 1; 

    if (secretnumberguess > secretnumber) { 
     printf("Your guess was greater than the secret number.\n"); 
    } 

    else if (secretnumberguess < secretnumber){ 
     printf("Your guess was less than the secret number.\n"); 
    } 

    else{ 
      printf("Your guess was equal to the secret number. You win!\n"); 
      flag=1; 
    } 
    } 

    if (guesses == 0 && flag==0) 
    printf("Sorry you are out of guesses. You lose.\n"); 

    return 0; 
}

这里可能是这个编码的简单方式。

read guesses; 

while (guesses > 0) { 
    read input; 
    if (input == secret) { 
    print "you win!!"; 
    return; 
    } 
    else { 
    print "try again!"; 
    } 
    guesses--; 
} 

print "Sorry! You are out of guesses";
