Question

我正在用C语言编写一个子手游戏，据我所知这应该可行。我的程序似乎经历了两次循环，似乎两次出现了问题，两次打印出语句并更改了已设置的布尔值。有人可以帮助我确定为什么会发生这种情况吗？

这是我的程序，后面是示例输出。

#include <stdio.h>
#include <string.h>
#include <stdbool.h>

int main()
{
    // setting the word to be guessed and a mutable version of it.
    const char secretWord[] = "programming";
    char workingString[sizeof(secretWord)];
    int guessCount = 6;

    // setting the mutable version of the string to be all stars.
    for (int i = 0; i<strlen(secretWord); i++){
        workingString[i] = '*';
    }

    printf("Welcome to Hangman!\nTry to guess the word one letter at a time.\n\n");

    //infinite loop.
    while(1){
        bool wrongLetter = true;
        bool hasStar = false;
        printf("# of misses left: %d\tword: = %s \n", guessCount, workingString);

        char letter;
        printf("Enter a letter: ");
        scanf("%c", &letter);
        printf("\n");

        // go through the array, see if any characters match.
        // replace character if they do, set 'wrong letter' to false so no penalty is applied.
        for (int i = 0; i<sizeof(secretWord); i++){
            if (letter == secretWord[i]){
                workingString[i] = letter;
                wrongLetter = false;
            }
        }

        // check to see if the string is solved or not.
        for (int i = 0; i<sizeof(workingString); i++){
            if(workingString[i] == '*')
                hasStar = true;
        }

        // check boolean to see if a star was found
        if (!hasStar){
            printf("You won! Game Over!\n");
            break;
        }

        // check boolean to see if a wrong guess was made.
        if(wrongLetter)
            guessCount--;

        // check to see if user lost.
        if(guessCount==0){
            printf("YOU LOSE! The word is: %s\n",secretWord);
            break;
        }
    }

    return 0;
}

这是我运行的示例输出。由于该程序由于某种原因两次进入循环，因此语句加倍。

Welcome to Hangman!
Try to guess the word one letter at a time.

# of misses left: 6 word: = ********** 
Enter a letter: a

# of misses left: 6 word: = *****a**** 
Enter a letter: 
# of misses left: 5 word: = *****a**** 
Enter a letter: p

# of misses left: 5 word: = p****a**** 
Enter a letter: 
# of misses left: 4 word: = p****a**** 
Enter a letter: r

# of misses left: 4 word: = pr**ra**** 
Enter a letter: 
# of misses left: 3 word: = pr**ra**** 
Enter a letter: o

# of misses left: 3 word: = pro*ra**** 
Enter a letter: 
# of misses left: 2 word: = pro*ra**** 
Enter a letter: g

# of misses left: 2 word: = progra****g 
Enter a letter: 
# of misses left: 1 word: = progra****g 
Enter a letter: m

# of misses left: 1 word: = programm**g 
Enter a letter: 
YOU LOSE! The word is: programming

我所做的所有猜测都是正确的，但是程序再次循环并认为错误。

C-程序两次遍历for循环，更改布尔值
