...and your question is...?

[RedSon]

Um....what is your question?

Ganon, did you delete this poor kid's question?

Nossir, I added code tags and that is all. Made it easier to read, you see.

You can't use == to compare strings. you need to use strcmp or strncmp (which I think is in string.h)

strcmp compares 2 null termintaed strings and returns 0 if they are the same. I'm not sure you can rely on this, but normally the way it works is to return the difference of the first unlike character, so if the first string's first different character has a lower ascii code than the seconds a negative number is returned, otherwise a positive)

strcmp is not a 'safe' method because it expects the null terminator, so it is better to use strncmp. srncmp is much the same except it takes an extra argument of a length to compare over (and thus avoiding the problem of needing terminated string) making it a little more difficult to use , but checking that the length of 2 strings are the same can quickly tell you that they are NOT the same (but not necessarily ARE).

Oh I thought your delete button might be right next to the one labeld [code]
