One liner to produce string of n '?'s separated by commas ... ?

[Richard Gration]

Anyone for golf?

I can't think of anything shorter

$n = 10;
$vals = join ',', split //,'?' x $n;

In case anyone was wondering, this _is_ SQL related ;-)

$n = 10;
$vals = join ',', split //,'?' x $n;

How about:
$n=10;
chop($vals = '?,' x $n);

/jN

Why bother creating a string only to spilt it?
$vals = join ',', ('?')x10;

Well, that's kinda what prompted me to ask

$vals = join ',', ('?')x10;

The idea of using ('?') x 10 never occured to me. My mind did not suggest
it as valid syntax. Excuse me while I read perlop ...

{ local $" = ',';
$vals = "@{[ ('?') x $n ]}";
}

$n = 10;
$vals = join ',', split //,'?' x $n;

Yet another way:

print join ',', map('?', 1..10)

There's not much in it, I'd just rather avoid the extra block, my personal
aesthetic choice ...

$vals=("?,"x9)."?";

Short, but no good for $n == 0.
