Hi, I'm sorry to be asking such a daft question but I need a concept
explaining....


I'm working through the excellent Chris Pine book 'Learn to program' and
I don't get one of the examples he gives.  In particular I don't follow
the following example:


def say_moo number_of_moos
  puts 'mooooooo...' * number_of_moos
  'yellow submarine'
end

x = say_moo 3
puts x.capitalize + ', dude...'
puts x + '.'

Now the output from this is:

mooooooo...mooooooo...mooooooo
Yellow submarine, dude...
yellow submarine

-------------

OK, so here's the problem, I _don't_ get why it doesn't return the
following:


mooooooo...mooooooo...mooooooo
Yellow submarine, dude...
mooooooo...mooooooo...mooooooo
yellow submarine

-------------

Why do we get one set of 'moos' but not a second?

Sorry for such a newbiee question.

Cheers

arfon
