What's the difference between a hash and hash reference in Perl?
Hi,
Trying to understand the concept of hashes in perl The sample code is given below :
#!/usr/bin/perl
use strict;
use warnings;
my %hash =();
%hash = ();
my $hash_ref = {};
$hash_ref->{dhg} = 'jhfkjd';
print $hash_ref->{dhg} . "\n";
$hash{abc} = 'def';
$hash{key2} = 0;
print "$hash{abc}\n";
I get the output as:
jhfkjd
def
I wanted to know what is the difference between $hash_ref and %hash that I have used, although I know it syntactically.
I am absolutely new to perl. Any help will be valuable .
Thanks & Regards,
Tazim.
