Re: Formatting with sprintf

sprintf doesn't apply

#!/usr/bin/perl

# http://perlmonks.org/?parent=1147312;node_id=3333

use strict;
use warnings;
$| = 1;

my $card = '1234543267679898';

my $CCformatted = $card =~ s/....\K\B/-/gr;

print $CCformatted, "\n";

What version of perl are you running? `\K` was introduced to regular expressions in v5.10.0. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l]

Old perl ? `my $CCformatted = join '-', $card =~ /..../g;` [download] Most of my PP hours were in Citabria's, but that was 41? years ago :)	[reply] [d/l]
