Write a method which takes a block and calls it once for each hour that has passed today. That way, if I were to pass in the block do puts ‘DONG!‘ end, it would chime (sort of) like a grandfather clock. Test your method out with a few different blocks (including the one I just gave you). Hint: You can use Time.now.hour to get the current hour. However, this returns a number between 0 and 23, so you will have to alter those numbers in order to get ordinary clock-face numbers (1 to 12)..
Why proc instead of method?
