I got Pset5 Speller to work correctly but I am getting a Valgrind error as follows 568 bytes in 1 blocks are still reachable in loss record 1 of 1: (file: dictionary.c, line: 108) for all the words. What could be the problem?

Line 108 is in the load function where I am opening the dictionary

bool load(const char *dictionary)
{
    FILE* fp = fopen(dictionary, "r");  #108
........... fclose(fp);
    return false;
}

Sorry, not sure how to help (yet) with this one!

Without seeing more code, it's hard to know. A leak of 568 bytes in 1 block usually indicates a file that wasn't closed. Is it possible that there's a return command executed before the dictionary file was closed?

  • Yes! I was returning true in an if condition before closing the file! Thank you so much :D
