Im making a hangman game in C, and two of its functions dont seem to be working. The code is below, the troublemakers are int check_guess and int hidden_word the others seem to work fine on their own. For some reason the check_guess function doesnt determine if a guess is correct or not and the hidden_word function barely works.
int main(int argc, char **argv)
{char wordfile[256], option, temp[256] ;
char wordlist[MAX_WORDS][MAX_WORD_LENGTH] ;
int num_words, result ;
Game g ;`
// seed the rand() function first
srand ( time(NULL));
// check to see if command line argument was given, if so use it as the filename for the words
if ( argc > 1 ){
strcpy ( wordfile, argv[1] ) ;
} else {
strcpy ( wordfile, "wordlist.txt" ) ;
}
// now read word file
num_words = read_words ( wordfile, wordlist ) ;
if ( num_words == 0 ){
printf ( "No words were read from file, exiting\n") ;
exit ( -1 ) ;
}
printf ( "Read %d words from file\n", num_words ) ;
do {
setup_game ( &g, wordlist, num_words ) ;
result = play_game ( &g ) ;
printf ( "Would you like to play again (y/n)? " ) ;
scanf ( " %c", &option ) ;
fgets ( temp, 256, stdin ) ; // read the rest of the line to get rid of it from stdin
} while ( option == 'y' || option == 'Y' ) ;
return 0 ;
}
