I was successfully able to set break points and execute the program step by step without any problems using gdb. Maybe you're not doing that correctly. I recommend you watch the short on gdb for more …

So you need the size to load and you need to load to know the size. This seems infinite. My suggestion would be using the maximum value that your hash function returns as the size of your hash table …

An argument is a variable/ a value that is passed to a function when it's called. It actually has nothing to do with what you're describing. Now, for your question, you could actually do something li …

if you read the switch statement at the beginning of the program, you'll know that the -h option lets you know how the program should be used. 'h' stands for "help". this is also typically the case wi …

try executing this: sudo chown -R jharvard:students ~cs50/pset6 and try again! …

Okay, here's the thing: this is how you're inserting a new node into your hash table int index = hashfun(new_node->WORD); new_node->next = hashtable[index]->next; hashtable[index]->next = new_node; …

If you remember from previous weeks, fscanf() by itself is actually not the best function to use to get input specifically strings. fgetc() reads character-by-character from a stream. This will enabl …

They, however, expect something a little bit more complicated than this if you chose to implement a hash table for pset6. …

When the word "Agetribe" is in the dictionary, but the word "Agetribe's" or "Agetribes'" are not, your program should consider "Agetribe's" and "Agetribes'" as a misspelled words and vice-versa unless …

Should I try to improve it more? Yes, if you wish! Does it matter? It's meant to challenge the staff and yourself at the first place, so officially it doesn't matter. If I should improv …

You're totally correct. You have to initialize variables before asking for their values. Since a trie is an array of arrays, the root array can be initialized when declared like that node *root[26] …

To initialize an array with an initialization list, you must do that in the same statement that declares this array as follows int arr[] = {1, 2, 3, 4, 5}; Since your array is a member of a struct, …

You don't compare strings using the relational operators, but rather, you may use strcmp (declared in string.h). Also, apparently there's a problem with the logic of the insertion here. For example …

According to valgrind, an invalid read of size 4 was made exactly at dictionary.c, function addTrie, line 256. "If ptr is NULL, no operation is performed" Apparently, this invalid read is the same one …

That program that you're trying to compile doesn't have a main function.
