Hi all, I write the following problem to see if you can clarify me:
How I can modify an attribute of an object in a method?, Eg:

class Klass
=C2=A0attr_accessor: attribute

=C2=A0def initialize (number)
=C2=A0 =C2=A0@attribute =3D number
=C2=A0end

=C2=A0def get_attribute
=C2=A0 =C2=A0return @attribute
=C2=A0end
end

object =3D Klass.new(5)

def adder(attribute)
=C2=A0return attribute +=3D 1
end

while true
=C2=A0puts adder(objeto.get_attribute)
end

I explain: I want the attribute @attribute (which I pass as a parameter
to the method adder) will be modified in the method adder (adding 1)
constantly, printing its output in the while cycle.

If you use attr_accessor, it just gene= rate something like below:

# getter

def = attribute

=C2=A0 =C2=A0 @attribute

end

# setter

def attribute=3D(value)

=C2=A0 =C2=A0 @attribu= te =3D value

end

So you can do anything = you like with setter method.

(If I didn't misunderstand your = requirement)

=C2=A0

In this case only 6 returns me constantly, that is, sum once and then
stop adding. As I can do in this case?

Sorry for bad english :)
