Hi guys,
I'm trying to assign the value of a key in a hash to a variable but want to use a hash reference. Without dereferencing the hash before on a separate line, how could I assign the value of the key to the variable while dereferencing at the same time?
Here is some code:
#!/usr/bin/perl
use warnings;
use strict;
# defines country => language hash
my %langs = ( England => 'English',
France => 'French',
Spain => 'Spanish',
China => 'Chinese',
Germany => 'German');
my $countryid = 'England';
my $langsref = \%langs;
# get language of England
my $englishlang = %{ $langsref }{$countryid}; # <---- this doesn't wo
+rk. I wanna do the assignment all in this one line but can't figure o
+ut assigning while dereferencing.
print $englishlang;
Any help would be great. Thanks so much!
