Monks,

I'm confused of how to use the references in conditional statements like 

#!/usr/bin/perl
use strict;

my $hash_ref = &getHashRef();

# Check if hash reference has really values in it....
if ( $hash_ref ) {
    .....# do something
}

I want to do the processing only if there is data inside the $hash_ref. eventhough there is no data inside the hashref, it is going into the loop, which it should not be.

I'm trying the following ways. .. 


# Which one is correct .....
if ( %$hash_ref ) {
    ......
}

# OR

if ( $hash_ref ) {
    ........
}

Also please provide me check for existence of values inside Array references.....
