All words are misspelled even with the dictionary is loaded. Help?

Question

Im not quite sure what is the problem with checking the words in the dictionary against loaded texts. All words within in the loaded txts return mispelled even with my dictionary loaded with the right number of words. I searched through other responses similar to this question but i couldn't find anything helpfull to debug my dictionary.c. Could someone (anyone) please point me into the right direction to fix this? Any help would be appreciated.

UPDATED code, with applied fixes.

UPDATE: I have followed the first three pointers Cliff has given me(and they work as expected), but I am still having trouble implementing number 4. Below is what what I've tried, but to no avail I am still having the same output as before.

int s = strlen(word);
char checker[LENGTH + 1];

for(int i = 0; i < s; i++)
    checker[i] =  tolower(word[i]);

checker[s] = '\0';    

Answer 1

In your load, when your hashtable[key]->next isn't null, you do this:

    new_word->next=head; 
    head = new_word;

what is head at this point? Last time you set it, it was for the first node in your linked list. As such, you are overwriting the first node in that bucket and end up throwing away some words.

Shouldn't you be using hashtable[key]->next? And not head?

Answer 2

Here are some pointers in the right direction:

1. The large dictionary is hardcoded. Should be using parameter passed to load() as the dictionary.
2. All words are hashing to 0 because word is empty. (new->word vs. word)
3. Word count is off by 1. Code reads a line from dictionary file, processes it, and then checks for EOF. This results in one extra word in the count and last word being processed twice.
4. In check(), no end of string marker set in checker[], causing strcmp to always fail.

There is at least one more problem, but this will get you going. :-)
