Suggested Ruby coding:

% cat assign.rb

#!/usr/bin/env ruby
class RubyLesson
        def initialize(number)
                @number = number
        end
        def roundNumbers
                remainder = "[EMAIL PROTECTED]".to_i % 5
                base_amount = "[EMAIL PROTECTED]".to_i - remainder
                if ( remainder > 2 )
                        print "The number ", "[EMAIL PROTECTED]".to_i, " is rounded to ", 
base_amount + 5, "\n"
                else
                        print "The number ", "[EMAIL PROTECTED]".to_i, " is rounded to ", 
base_amount, "\n"
                end
        end
end
s = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
s.each {
        |x|
        aRubyLesson = RubyLesson.new(x)
        aRubyLesson.roundNumbers
}

I'm not a ruby programmer, but can I ask why you'd make this part of a
class? Surely a function roundNumbers(x) would work just as well? The
whole class infrastructure seems rather redundant and makes what
should be simple code overly verbose.

Cheers,

Tim

Run as:

% ./assign.rb
