Subject: Re: how do i add  an instance variable to a class in Ruby

In class1.rb and class2.rb you create templates for the classes.
To display @a you must:
1- require class1.rb and class2.rb
2-istantiate the class Sumit
3-call the method aos
as in:
irb
irb(main):001:0> require 'class1'
=> true
irb(main):002:0> require 'class2'
=> true
irb(main):003:0> c2=Person::Sumit.new # istantiate the class
=> #<Person::Sumit:0x2d89c58 @a=10>
irb(main):004:0> c2.aos               # display variable @a
10
=> nil
irb(main):005:0> quit
