Question

I really have tried researching this problem, but I’m now getting so close to it I fear I won’t find the solution without asking for help. I’m going through RubyMonk and one of the exercises has me completely stumped.

class Hero
  def initialize(*names)
    @names = names
  end
  def full_name
    # a hero class allows us to easily combine an arbitrary number of names
  end
end

def names
  heroes = [Hero.new("Christopher", "Alexander"),
            Hero.new("John", "McCarthy"),
            Hero.new("Emperor", "Joshua", "Abraham", "Norton")]
  # map over heroes using your new powers!
end

You can see in the comments what the code is asking for; take the names in the heroes variable and combine them into a single name. I’ve tried testing some puts and am unable to get anything in the STDOUT besides “#” or “nil” so clearly I am not working with it correctly.

The requirements for the goal say not to use .map or .collect but I think you actually are supposed to because it fails a requirement if you don’t use .map or .collect.

Ideas?

Answer 1

class Hero
  def initialize(*names)
    @names = names
  end
  def full_name
    @names.join(' ')
  end
end

def names
  heroes = [Hero.new("Christopher", "Alexander"),
            Hero.new("John", "McCarthy"),
            Hero.new("Emperor", "Joshua", "Abraham", "Norton")]
  heroes.map(&:full_name)
end
