Need help regarding strcmp. - rangerxxll - 28.04.2014

I don't really need help, I just have a question really. I attempted to create a simple dialog that will create a pickup if "pickup" is entered as inputtext. The first time I did it, it was this:

pawn Код:

if(strcmp("pickup", inputtext, true))

I tested it in-game and it didn't work. So I added a ! just for the hell of it (Which I assumed means "Doesn't" or "Not"). It seemed to work after this was added.

Anywho, I tried reading it and to me it says "If string compaired is not... blah blah." Why is ! neccessary when compairing strings?

Quote:

Return Values:
-1 if string1 comes before string2
1 if string1 comes after string2
0 if the strings are the same (for the matched length).

As for why returning 0 means the strings are equal, the two strings are compared in lexicographic (alphabetical) order.

So there can be 3 possibilities: the 1st string comes before the 2nd string in a dictionary, both are equal, or the 1st string comes after the 2nd string. To me it would make more symmetric sense to return the values -1, 0, 1 rather than 0, 1, 2.

I know this has been already answered above, but for simplicity's sake -

Matched strings return 0. ! (0) returns a true condition. That's why..
