I'm trying to create a class, which has a constructor that takes a single argument. When I create a new instance of the object, it returns a pointer.
class Adder
def initialize(my_num)
@my_num = my_num
end
end
y = Adder.new(12)
puts y
What am I doing wrong?
Thanks

When you use
new
method, you get 'reference' on newly created object.puts
kernel method returns some internal ruby information about this object. If you want to get any information about state your object, you can use getter method:Or you can use 'attr_reader' method that define a couple of setter and getter methods behind the scene:
