pawn Код:

IsConnected[playerid] = (IsPlayerConnected(playerid)) ? 1 : 0;

(IsPlayerConnected(playerid)) is the if statement
? is pretty much the opening bracket
: is the else statement

For strings you'll need to enclose it in parenthesis, ex:

pawn Код:

PlayersRank[playerid] = (IsPlayerAdmin(playerid)) ? ("Administrator") : ("Player");

Well basically it's an if-statement in an expression. For example:

pawn Код:

new val = 4;
new otherval;
if(val == 8)
{
    othervalval = 6;
}
else
{
    othervalval = 12;
}

Could also be written as:

pawn Код:

new val = 4;
new otherval;
otherval = (val == 8) ? (6) : (12);

The hooks are optional, but I usually add them to keep code readable.

In the case of if-else if-else statements:

pawn Код:

if(a == 4)
{
    b = 8;
}
else if(a == 3)
{
    b = 13;
}
else
{
    b = 2;
}

becomes...

pawn Код:

b = (a == 4) ? (8) : (a == 3) ? (13) : 2;
