I think

pawn Код:

CMD:connected( playerid, params[ ] )
{
    if( IsPlayerConnected( playerid ) )
        return SendClientMessage( playerid, -1, "You are connected." );

    return SendClientMessage( playerid, -1, "For some reason, you are not connected." );
}

is better (at least shorter) than

pawn Код:

CMD:connected(playerid, params[])
{
    if(IsPlayerConnected(playerid))
    {
        SendClientMessage(playerid, -1, "You are connected.");
        return 1;
    }
    else
    {
        SendClientMessage(playerid, -1, "For some reason, you are not connected.");
    }
    return 1;
}
