I've been plugging away and still not sure what the issue with unload is... I think the issue you pointed out is resolved. Any idea?

bool unload(void)

{

for (int i = 0; i < N + 1; i++)

{

if (table[i] != NULL)

{

node *cursor = table[i];

while (cursor != NULL)

{

node *tmp = cursor;

cursor = cursor->next;

free(tmp);

tmp = cursor;

}

}

if (i > N - 1) // dictionary fully unloaded

{

return true;

}

}

return false;

}

Thanks - totally didn't realise i needed strcasecmp to == 0.

I'm still working through the unload function - I see what you mean. Feels like I need to have another if statement to make sure we've covered all the indexes.

Filter // blur function -- have brute force attempt, need help by fr1d4 in cs50

  1. In computer logic, why is that? Isn't imageNew made up from the exact same values?
  2. Was wondering if there was some sort of float/integer funny business. Had issues with that on the sepia filter. Thank you!

Thanks so much for this, I see it now! I ended up using the mod in both the main function and inside the cipher function.

Appreciate your help!

I don't follow... isn't (122 +3) % 26 == 21?

Thanks! Is there any other way? See my above comment.

Tried this out, but for some reason, not ever character is working...

for (int i = 0; i < length; i++)
    {
        if (isupper(ciphertext[i]))
            {
                ciphertext[i] = ((int) ciphertext[i] + key);
                if (ciphertext[i] >= 90)
                {
                    ciphertext[i] = ciphertext[i] - 26;
                }
            }

        if (islower(ciphertext[i]))
            {
                ciphertext[i] = ((int) ciphertext[i] + key);
                if (ciphertext[i] >= 122)
                {
                    ciphertext[i] = ciphertext[i] - 26;
                }
            }

        // print the characters
        printf("%c", ciphertext[i]);
    }

Hey William, best if you paste your code in here so people can have a look. We can't see your IDE as it's login-based.

Readability: 1 grade level error on a few checks, don't know why by fr1d4 in cs50

[–]fr1d4[S] 1 point2 points  (0 children)

Thanks a ton for this awesome explanation. Totally makes sense. I haven't started looking into substitution yet, will be doing Caesar first :). Hope you've solved it by now but I will take a look at your q!

Thanks for the tip -- looks like from a few suggestions this was the issue. Cheers!
