# This is the goal
#%Belfast_car_dealer_hash = ("Toyota"=> 1,
# "Chrysler" => 1);
# "Ford" => 1);
The following will initialize your hash the way you want:
my %Belfast_car_dealer_hash = map { $_ => 1 } @dealers[1,3,4];
Dumper output of %Belfast_car_dealer_hash:
$VAR1 = {
'Chrysler' => 1,
'Toyota' => 1,
'Ford' => 1
};
Update: Added [1,3,4] to limit key creation.
My apologies; I believe I've misunderstood. What about using a hash of arrays, where the key is the city and the value is a reference to an array of dealers? Perhaps this data structure would be helpful:
use strict;
use warnings;
my @dealers = ( "Nissan", "Toyota", "Tesla", "Chrysler", "Ford", "Gene
+ral Motors" );
my %citiesDealers = (
'Belfast' => [ @dealers[ 1, 3, 4 ] ],
'Dublin' => [ @dealers[ 2, 3, 0 ] ],
'Cork' => [ @dealers[ 0, 3 ] ],
'Derry' => [ @dealers[ 1, 4, 2 ] ],
'Tralee' => [ @dealers[ 2, 1, 0, 5 ] ]
);
print $_, "\n" for @{ $citiesDealers{'Belfast'} };
Output:
Toyota
Chrysler
Ford

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
