Re: What would be the easier way

in reply to What would be the easier way

Use a hash table with an array ref for each entry, doing something like push @{ $height{$input} }, $value; after parsing each line into $input and $value; leaving you with something like this:

%height = (
  'house' => [
               string1,
               string2
             ],
  'table' => [
               string3,
               string4
             ]
)

and @{$height{house}} would be all the values for house in an array

`@{ $whatever }` de-references the array ref `$whatever` so you can use the reference as an array. Your data are contained in array references which you need to de-reference with `@{ }` to use as arrays.	[reply] [d/l] [select]

That is not an array, but an array reference.	[reply]

You pronounce that height-of-$input or height-of-house or height-of-table See Re: What are the most basic, generic aspects of programming?, Re: Perl Best Practices for naming variables, About the use of the plural form for the name of variables	[reply]
