  2) Which class would you modify if you wanted
  all Smurfs to be able to change the Song 
  they can sing?




  3) Which class would you modify if you wanted
  Smurfette to be the only smurf which can
  change its song?




  4) How would you change AgedSmurf::IsPapaSmurf()
  if gender was private instead of protected?
