need help in ternary operator - newbienoob - 24.08.2013

I'm not really good in TO so I'm not sure what could be the reason of this problem.

pawn Code:

(db_num_rows(Result)) ? ShowPlayerDialog(playerid, dlogin, DIALOG_STYLE_INPUT, ""horange"LOGIN", "test", "Login", "Quit")
        : ShowPlayerDialog(playerid, dregister, DIALOG_STYLE_INPUT, ""horange"REGISTER", "test", "Register", "Quit");

Code:

warning 215: expression has no effect

Youre using a long length how about strcat

Re: need help in ternary operator - newbienoob - 24.08.2013

Nope. If I did this

pawn Code:

(a == b) ? c = d : c = e;

I'll still get the same warning.

make them in format string

Sorry, but I don't understand you. You mean, the dialog?

EDIT: Edited main post.

I don't see the point of using the ternary syntax for something like that just use if/else it makes absolutely no difference once it's compiled.

pawn Code:

if(db_num_rows(result))
{
    ShowPlayerDialog(.....);
}
else
{
    ShowPlayerDialog(.....);
}
//Looks ugly

(db_num_rows(result)) ? ShowPlayerDialog(....) : ShowPlayerDialog(....);
//Looks simple and clean!

That would be something like

pawn Code:

c = (a == b) ? d : e;

I'll edit this for the main post

Ternary operators are useful in many, many cases, but they _don't_ make your code easier to read.
