Question

I think I’m on the right track, but when I try to call for p.first_name. I get an error which can be seen in the screenshot, does anyone know what I’m doing wrong?

Here is a link if you can’t see it: http://snag.gy/pj6ny.jpg

Here is the code:

class Person 

    def initialize (first_name, last_name, age)  
        @first_name = first_name  
        @last_name = last_name
        @age = age  

    end  
end

Everything is fine when I enter

> p = Person.new("Earl", "Rubens-Watts", 2)

but it goes weird after that. Desired output is:

 > p = Person.new("Earl", "Rubens-Watts", 2)
  > p.first_name
  => "Earl"
  > p.last_name
  => "Rubens-Watts"
  > p.age
  => 2

Thanks!

You haven’t defined a first_name method or declared any attributes. Try this:

class Person 
    attr_reader :first_name, :last_name, :age
    def initialize (first_name, last_name, age)  
        @first_name = first_name  
        @last_name = last_name
        @age = age
    end
end
