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.
It's part of an effort to discipline my programming-mental-attitude to
think object-oriented.
So, eventually, it becomes natural and conforming with the concept that
Ruby is pure
object-oriented.
