我似乎无法弄清楚为什么当用户猜完所有字母时我的程序不会结束游戏。我知道问题出在 play() 函数中。关于在播放功能中更改什么或导致此问题的任何内容的任何指示？

#include    <stdio.h>
#include    <string.h>
#include    <ctype.h>
// MAXWORD, which will be the max word length 
#define     MAXWORD     10
// INCORRECT_GUESSES, which will be the max guesses
#define     INCORRECT_GUESSES   5

/* Prototypes */

// Fills theArray with howMany copies of theLetter
void    fill_array( char *theArray, int howMany, char theLetter );

// Get char from player, checks the letter, shows progress so far
int     get_letter( char *theWord, char *soFar );

// Check if letter is in word, updates progress so far
int     letter_in_word( char *theWord, char *soFar, char theLetter );

// Convert the word to lowercase
void    lower_string( char *someWord );

// Play one game
void    play( char *theWord );

/* Function definitions */

int main( )

    char theWord [ MAXWORD ];

    if ( word == NULL )

        printf( "No input file found..........\n" );
        return -1;
    }
    printf("Want to play a game?\n");
    fscanf( word, "%s", theWord );

    lower_string( theWord );
