Another sample exercise from chapter 4 from 'Learn to Program':

Sublime Text 2:


puts 'Yo, what up dawg?...hey what\'s yo favorite number?'
number = gets.chomp.to_i
mynumber = number + 1
puts 'What are you kidding me? '+number.to_s+' ???? .........'+mynumber.to_s+ ' really is a much better number!'

...And from terminal.
