I’m really new to Ruby and rather new to OOP in general. I’ve been
using Perl for about 7 years now and have a fairly good understanding of
that language. I’ve never really entertained Python to any serious
degree beyond ‘Hello World’. Now you know my background.
I tried to do the following:
and it failed in the irb.
My thinking is that 13 is a Fixnum class and Fixnum inherits Integer.
Integer has a method ‘lcd’ that returns the least common denominator.
Since Fixnum < Integer then all the methods of Integer should be
available to all the child objects (Fixnum and super). And if this is
true, then calling a method like I did (Fixnum#lcd) implies an
inheritance search to find that class.
But my thinking seems to not reflect Ruby very well.
Can someone please tell me what I did wrong in the code and also in
thought? It’s little niggly bits like this that get frustrating.
