Thread: Segmentation Fault Error

Need some help with my program, supposed to be based on a game of hangman. Where the words that are used come from a file "hMan.in"

Mind you, this is a very, very early version of my project. And when compiled, it gives me no errors, however, when I run it, just after typing in the letter and hitting enter it gives me a segmentation fault and exits the program.

Tried commenting out parts of the program to narrow down my problem.

Trouble starts right after I un-comment out the part starting with:

if ( isThere == 0)

Any help would be greatly appreciated!!!

Here's the current version of the program:

Code:

#define STRSIZ 10

int
main(void)
{

/* Declaring Variables */

char inputStr[STRSIZ];
char dashStr[STRSIZ];
char guessStr[STRSIZ];
char guess, choice;
int isThere = 0, counter = 0, i, j, question;
int k = 0, full;
FILE* file_in;

file_in = fopen( "hMan.in", "r" );

/* Do while loop for exiting program */

do
{
   /* Display the Greeting */

   printf(" --------------------- \n");
   printf("| Welcome to Hangman! |\n");
   printf(" --------------------- \n");

   /* Input word from file to string */

   fgets(inputStr, STRSIZ + 1, file_in);

   for (i = 0; i < strlen(inputStr); i++)
   {
      dashStr[i] = '_';
   }
   dashStr[i-1] = '\0';

   /* Loop for game play */

   do
   {

   /* Display word in dash form */

   printf("Here is your word: ");
   printf("%s\n", dashStr);

   /* Prompt user for letter */

   printf("Enter a letter: ");
   scanf( " %c", &guess);

   for ( i = 0; i < strlen(guessStr); i++)
   {

   fgets(inputStr, STRSIZ + 1, file_in);

   for (i = 0; i < strlen(inputStr); i++)
   {
      dashStr[i] = '_';
   }
   dashStr[i-1] = '\0';

   /* Loop for game play */

   do
   {

   /* Display word in dash form */

   printf("Here is your word: ");
   printf("%s\n", dashStr);

   /* Prompt user for letter */

   printf("Enter a letter: ");
   scanf( " %c", &guess);



   for ( i = 0; i < strlen(guessStr); i++)
   {
      if ( guess == guessStr[i])
      {
         printf("Error: Already guessed!\n");
         counter++;
         isThere = 1;
         break;
      }
      else
         isThere = 0;
   }

   if ( isThere == 0)
   {

      guessStr[j] = guess;

      for ( i = 0; i < strlen(inputStr); i++)
      {
         if ( guess == inputStr[i] )
         {
            dashStr[k] = guess;
            counter++;
         }
      }
   }

   for ( i = 0; i < strlen(dashStr); i++)
   {
      if ( dashStr[i] == '_')
      {
         full = 0;
         break;
      }
      else
         full = 1;
   }

   counter++;
   }
   while( (counter < 10) && (full != 1) );

   /* Asking user if they want to play hangman again */

   do
   {
      printf( "Would you like to play again? (y/n):");
      scanf( " %c", &choice);

      switch ( choice )
      {

         case 'y':
         case 'Y':
                 question = 1;
                 break;

         case 'n':
         case 'N':
                 question = 0;
                 break;

         default:
                 question = 1;
                 printf("Error: Invalid option!!!\n");
                 break;
      }
   }
   while( question != 0);
}
while( choice != 'n' && 'N');

return(0);
}
