Dear Monks,I have the following code. I want to handle Ctrl-C when waiting for $choice

# Handle Ctrl-C
$SIG{INT} = \&ctrlc;

use autodie;
use Modern::Perl;
use Storable qw {store retrieve};

my $dbfile = 'sbs.db';
my %person = %{ retrieve($dbfile) };

while() {
  print "\n(C)reate,(L)ist,(N)ew,(M)odify,(R)emove,(Q)uit? ";
  chomp(my $choice = <>);
  $choice = lc $choice;
  #
  # Some code here
  # 
  
}
exit;
  
sub ctrlc {
  store \%person,$dbfile;
  print "You used Ctrl-C!";
  exit 1;
}

When I press Ctrl-C, I get the following messages :

(C)reate,(L)ist,(N)ew,(M)odify,(R)emove,(Q)uit? Use of uninitialized v
+alue $choice in chomp at J:\ps
\monks.pl line 13.
Use of uninitialized value $choice in lc at J:\ps\monks.pl line 14.
You used Ctrl-C!

How can I avoid the error messages? And have a clean exit?
