What if i didnt use def?
Well I got this script:
puts “Do you feel, good, bad, or neutral?”
feelings = gets.chomp
STDOUT.flush
puts "You are feeling " + feelings
and I want to add the name class from this script:
puts “Hello, what is your name?”
name = gets.chomp
STDOUT.flush
puts "Hello, " + name
How would I do that?

If that’s the whole “script”, ‘name’ is a variable, not a class.
Again – find and work through a tutorial on basic Ruby.

That dog wouldn’t bark 
Maybe you should ask a more specific question, or run through a
basic tutorial on Ruby first.
truth that if he look like he want swat him on the nozzles
yes it lite trouble but there lab, can automatic every command dang.
thats make too of us. bouble dang, save a lot work uh auto speaker u
think that the directing. awersome we are save. p.s hi susan
hello anthony,
first, i completely agree with hassan that a basic ruby tutorial is
absolutely the best place to start. there are many very good ones
available - do a quick google search for “ruby tutorial.”
second, if i understand your question - try this:
#############
class NameGetter
attr_reader :name
def initialize
puts “Hello, what’s your name?”
@name = gets.chomp
puts "Hello, " + @name
end
end #class
class NameAndFeelingGetter
def initialize
## now you “call a class from another script…”
namegetter = NameGetter.new
## and get the “name” attribute
name = namegetter.name
##
puts “How do you feel?”
feelings = gets.chomp
puts “Well, #{name}, sounds like you’re feeling #{feelings}”
end
end #class
nfg = NameAndFeelingGetter.new
###############
then run the program…
happy ruby-ing…
