When using variables inside classes, only instance variables, which are prefixed with the `@` character, will be visible to all of the methods in the class. A variable that only exists inside of a code block or method is called a local variable. The whole concept is called scope.
Code Samples
class Name
attr_accessor :title, :first_name, :middle_name, :last_name
attr_reader :first_and_middle_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 full_name
@first_and_middle_name = @first_name + " " + @middle_name
@first_and_middle_name + " " + @last_name
end
def full_name_with_title
@title + " " + full_name()
end
end
name = Name.new("Mr.", "Jason", "", "Seifer")
puts name.full_name_with_title
