Team,

I would like to initialize some variables/arrays in a method, and access
them within another method.
For instance,


class My_Class

     def init_method(size)
          arr = Array.new(size)
          index = 1
     end # End method

    def print_method
       p arr
       p index
    end # End method

end # End class

my_obj = My_Class.new()
my_obj.init_method 10
my_obj.print_method


When I attempt to execute this code, I receive the error:

ruby My_Class
My_Class:9:in `print_method': undefined local variable or method `arr' for
#<My_Class:0x28ee87c> (NameError)
        from My_Class:17


I know the reason why it is happening, but I don't know how to access a
variable from another method, if there is a way.

Thank you

Victor
