--- I'm assuming that here you are defining the class that is
ResumeBuilder... you've got the @data and @fields that are instance
variables, right?  @data is an empty hash and @fields is an  array...

  def prompt

>       val = @data[field]
>       print "Please enter your #{field}#{(' (' + val + ')') if val}:"

--- Here you're defining the prompt method... and inserting each item from
the @field array into the hash... then you're putting the answer that is
given into the value for the item in the hash?  (wow, that's a hard one to
articulate when ya don't know all the lingo"  and then you are ending it if
val doesn't have anything?

  def confirm?

--- here is the confirmation section... You're telling the user what they
entered for each value by iterating through the hash/array?

resume = ResumeBuilder.new
> resume.prompt
> resume.prompt until resume.confirm?


and here you are defining that the variable resume is a new instance of the
Class ResumeBuilder... I'm kind of lost on the last line...

I didn't bother with the formatting, but you get the idea.

Will do!  Thanks for the input!  I'm finding that this is a really good way
to learn.
