Hello World.
This is my first forum membership, and first post.
I am learning Ruby.
It seems to be a very elegant an encompassing OO language.
I'm reading Thomas & Hunt: Classes, Objects, and Variables on-line.

See attached.

Regarding the following by the authors, and attached I see no
correlation.
However I've had very good results with attr_accessor.
Please help.

class Song
  def name
    @name
  end
  def artist
    @artist
  end
  def duration
    @duration
  end
end
aSong = Song.new("Bicylops", "Fleck", 260)
aSong.artist  » "Fleck"
aSong.name  » "Bicylops"
aSong.duration  » 260
------------------
class Song
  attr_reader :name, :artist, :duration
end
aSong = Song.new("Bicylops", "Fleck", 260)
aSong.artist  » "Fleck"
aSong.name  » "Bicylops"
aSong.duration  » 260
