[TUTORIAL] How to use ternary operators to shorten code.

[greentarch]

Hi, this is a tutorial how to use Ternary Operators.

Let's use an example :

Code: [Select]

new
    a = 0;

if ( a == 0 ) {
    a = 1;
}
else {
    a = 2;
}

Can be shorten to :

Code: [Select]

new
    a;

a = (a == 0) ? 1 : 2;

Let's break it out.

Code: [Select]

a = (a == 0)   ?   1   :   2;

--
( a == 0 ) -> If a == 0
--
? -> Then
--
1 -> Set it to 1. ( No ';' here )
--
: -> Else
--
2; -> Set it to 2. ( Now, there's a ';' here )
--
That was easy!

More examples :

Code: [Select]

SetPlayerTeam( playerid, ( pro[ playerid ] == true ) ? TEAM_PRO : TEAM_NOOB );

SendClientMessage( playerid, -1, ( pro[ playerid ] == true ) ? ( "You are a pro." ) : ( "Noob." ) );
                                                                                             // ^ you need brackets for strings
Hope I helped.

I think of it like math to be honest, not that complicated is it?

Yes, it is like math. And it's not that complicated if you understand
