Trying to match the what is contained in $what 3 consecutive times.
But I am getting the followoing error:
Use of uninitialized value $_ in pattern match (m//) at ./ex9-1.pl line 7.
The program:
#!/usr/bin/perl
use warnings;
use strict;
my $what = 'fred|barney';
if (/($what){3}/) {
# This is a short cut of:
if( $_ =~ m/($what){3}/ ){
# $_ has nothing in it
print $what;
# If you want what was matched:
if( m/((?:$what){3})/ ){
print $1, "\n";

Programming is as much about organization and communication
as it is about coding.
