Hi,
Somewhere in the code you have written
puts asong.name
puts asong.duration
When I run these lines basically it gives me some address in the memory
location ( or atleast that's wot I understand)
How does it help using puts in this manner? I am sure there is a reason
behind doing this? What is the advantage?
Thanks,
Vidhi.

Try this:
class Song
attr_reader :name, :duration
attr_writer :name, :duration
def initialize ( name, duration)
@name = name
@duration = duration
end
def print
puts "The song title is #{@name} and the track
length is #{@duration} "
end
def set_duration( newduration)
@duration = newduration
end
end
asong = Song.new( "Good Golly Miss Molly", 240)
asong.print
puts asong.name
puts asong.duration
The problem is the embracement in print:
below
> puts {"The song title is #{@name} and the
> track length is
> #{@duration} /n" } <- and here
Also be wary of using variables with the same name as
methods as in e.g. duration since Ruby will try and
evaluate the variable as a method or vice versa
dependant on where you are in the code.
