What's the difference? - Galcio - 21.12.2009

Hi, I'm quite new to coding in SAMP, I don't know if this sounds silly or not, whatever. I just wonder what the difference is between:

pawn Код:

if (!strcmp(cmdtext, "/example1", true))

and

pawn Код:

if (strcmp("/objective", cmdtext, true, 10) == 0)

Basically, what's the difference between "!strcmp" and "strcmp"?

Actually i don't know, because i never had used strcmp.
Better use dcmd or zcmd. It's faster and better.

Thanks.. but that didn't answer my question at all. If somebody knows, please reply as I'm interested in knowing it.

It's for checking if function returns false.

pawn Код:

if(IsPlayerConnected(playerid))
{
  // Player is connected
}

pawn Код:

if(!IsPlayerConnected(playerid))
{
  // Player is not connected
}

In your case "strcmp() == 0" is the same as "!strcmp()", because false is 0.

Thanks.. but if I want to make a teleport command, which one would you use? !strcmp or strcmp?

They both do the same, just in different ways.

It's the same if you use your first or second example.

Use zcmd command processor for commands - http://forum.sa-mp.com/index.php?topic=116240.0 - (it's simple and faster than strcmp)

simple, the ! char represents the "not".
(1 < 2), true. (1 is smaller)
(1 == 2), not true. (1 equals 2 ?)
!(1 == 2), true. (1 is NOT equal 2)
(1 > 2), not true. (1 greater 2 ?)
!(1 > 2), true. (1 NOT greater 2)

If theres and "!" infront of anything its the oppersit than without?
you get it?

Re: What's the difference? - MPKaboose - 21.12.2009

! means is not equal whit like 2 != 3

in you're case ! in front of the function means 0
