Hi, My code is not passing, when I follow the video. Please help.
class Name def initialize(title, first_name, middle_name, last_name) @title = title @first_name = first_name @middle_name = middle_name @last_name= last_name end
def title @title end
def first_name @first_name end
def middle_name @middle_name end
def last_name @last_name end end
name = Name.new("Mr.") puts name.title + " " + name.first_name + " " + name.middle_name + " " + name.last_name
I get the following error message, and I do not understand why.
name.rb:2: in 'initialize': wrong number of arguments (given 1, expect 4) (ArgumentError) from name.rb:26:in 'new' from name.rb:26:in '<main>'

name = Name.new("Mr.")
The error says you are only supplying one argument and it's expecting four. The reason it's expecting four is because of this code snippet near the top:
def initialize(title, first_name, middle_name, last_name)
@title = title
@first_name = first_name
@middle_name = middle_name
@last_name= last_name
end
The initialize method has four arguments, and so when you create an instantiation of the class Name (as shown above) you need to add the necessary arguments:
name = Name.new("Mr.", "Joe", "William", "Simpson")
I hope that helps you understand the error and how to fix it in the future.
