Perl string in Quote Word?

Seem like my daily road block. Is this possible? String in qw?

#!/usr/bin/perl

use strict;
use warnings;

print "Enter Your Number\n";
my $usercc = <>;

##split number
$usercc =~ s/(\w)(?=\w)/$1 /g;

print $usercc;

## string in qw, hmm..

my @ccnumber = qw($usercc);

I get Argument "$usercc" isn't numeric in multiplication (*) at

Thanks

Instead of that, use 

my @ccnumber = split /\s+/, $usercc;

Which does what you probably want, to split $usercc on whitespace.

No.
From: http://perlmeme.org/howtos/perlfunc/qw_function.html

How it works

qw() extracts words out of your string using embedded whitsepace as the delimiter and returns the words as a list. Note that this happens at compile time, which means that the call to qw() is replaced with the list before your code starts executing.

Additionlly, no interpolation is possible in the string you pass to qw().
