Re^2: Required guidance to simplify this program

hi 2teez.Thanks for your response.

for (@array) {
    $names{$_}++;
}

I would like to know what exactly this piece of code dose

You created a hash and inside the foreach loop i didn't get $names{$_}++ part.Please clarify.Thanks

[2teez]

For each name in the array, if the name already exists in the hash as key, then increment the value by 1; but if not, then add the name to the hash with the initial value of 1.
Hope it helps.

May be i am missing a basic understanding here.In order to understand what that block does practically i wrote a small program below

#!/usr/bin/perl -w
use strict;
my @array=qw(John Sue Larry Mary John Mary Larry John Joe Lisa John Ma
+ry);
my %hash;

foreach (@array)
         {
           $hash{$_}++;
          }
foreach (keys %hash)
          {
              print"Key is : [$_]\n";
           }
foreach (values %hash)
           {
                print "Value is : [$_]\n";
            }

After executing the code the output i got is

Output: key is :joe Key is :Lisa and so on..and value is no.of time they repeated. I realized the block of foreach array is assigning the list to hash but my doubt is nowhere i assigned array elements to hash and how come keys got assigned and values got assigned from array elements. I am new to programming.I guess i am missing basic understanding pardon me and guide. Thanks
