Perl hash containing arrays
Hi,
I am not that good at Perl.
But here's what I wanna do.
I want to create a hash where the keys would point to different arrays. This is what I have tried to do but in vain Smilie
Code:
@arr=(1,2,3);
@arr1=(3,2,1);

%hashOfLists=();
$hashOfLists{Key1}=@arr."\n";
$hashOfLists{Key2}=@arr1."\n";
#$hashOfLists{Key1}=1;
#$hashOfLists{Key2}=2;
print %hashOfLists;

Output
Code:
Key23
Key13

You probably meant

$hashOfLists{Key1}=\@arr."\n";
$hashOfLists{Key2}=\@arr1."\n";

But you don't print a hash like that. If you want to print the hash, consider

Code:
use Data::Dumper;
print Dumper(\%hashOfLists);

The newlines will mess that all up, should be:

Code:
@arr=(1,2,3);
@arr1=(3,2,1);

my %hashOfLists = (
   Key1 => \@arr,
   Key2 => \@arr1,
);
