  They take two variables-- the name of your event, and any data that goes along with your event.

  Since the input here is a char, we can't do
     data=="intact"
    or
     data=="broken"

  chars just don't play that way. Instead we're going to strcmp(), which compares two chars.
  If they are the same, strcmp will return 0.
