Question

how can I do in Ruby an array with indexes?
My custom from PHP is something like this:

@my_array = [0 => “a”, 3 => “bb”, 7 => “ccc”]

And this array I want to go through each_with_index and I would like to get the result, e.g. in a shape:

0 - a
3 - bb
7 - ccc

Can anyone help me, how to do?
Thanks

They’re called hashes in ruby.

h = { 0 => "a", 3 => "bb", 7 => "ccc" }
h.each {|key, value| puts "#{key} = #{value}" }
