strcmp help - is string1 the same as string2 - Jack_Leslie - 12.09.2011

Hi guys. I tried using this page as help: https://sampwiki.blast.hk/wiki/Strcmp

For this code:

Код:

if(!strcmp(BizInfo[PlayerInfo[playerid][pBizKey]][bOwner],PlayerName(playerid),true))

But I still can't get it to work. It's meant to ask if string1 IS NOT the same as string2, then proceed with the code below. But it won't work.

change
if(!strcmp(BizInfo[PlayerInfo[playerid][pBizKey]][bOwner],PlayerName(playerid),true))
to
if(strcmp(BizInfo[PlayerInfo[playerid][pBizKey]][bOwner],PlayerName(playerid),true))

... it returns 0 if the string matches, thus by having the "!" its checking if the string matches.

Oh yeah, course, that worked, thanks.

strcmp can return values less than 0 too. To correctly check if string1 does not match string2, use this:

pawn Код:

if(strcmp(BizInfo[PlayerInfo[playerid][pBizKey]][bOwner],PlayerName(playerid),true) != 0)

if you imagine strcmp as plain text then it'd be "can i compare these two strings?" and then it's easier to imagine no i can't compare them because they're the same.
It seems a quite a few people when they start out think of it as "are these two strings the same?"

when you don't use a condition it's check if the result is different than 0, not more.

so ****** is right then, since -1 would also work his way.
