Question

I have a hash table with the following contents:

my %hash = (
  'a' => 1,
  'b' => 2,
  'c' => [3, 4, 5],
);

And later on I’m pulling $hash{'c'} into @array_c as part of fetching function such as:

sub getVar {
  my $id = shift;
  return $hash{$id};
}

my @array_c = getVar('c');

Then later on I’m attempting to loop through @array_c and print each line:

foreach (@array_c){
  print "$_";
}

However instead of the desired output of 345, I get ARRAY(0x100804ed0)

Please help 😀

EDIT:

If I do print @array_c[0]->[0] then I get 3, so I guess I’m a little confused as to how I’ve managed to create a nested array.

SOLVED:

Went with deferencing the array:

my @array_c = @{getVar('c')};

Answer 1

The sub getVar returns a refrence to an array, just dereference it:

my @array_c = @{getVar('c')};

or change the sub:

sub getVar {
  my $id = shift;
  return @{$hash{$id}};
}
