  5. * DETERMINE IF DATE IS MAGIC
  6. * ____________________________________________________________
  7. * This program asks for a month (in numeric form),
  8. * a day, and a two-digit year, then checks if the month times
  9. * the day equals the year.
  10. *
  11. * Computation is based on the condition:
  12. * isMagic = (month * day == year)
  13. * ____________________________________________________________
  14. * INPUT
  15. * month : The month in numeric form (as an integer)
  16. * day   : The day of the month (as an integer)
  17. * year  : The two-digit year (as an integer)
  18. *
  19. * OUTPUT
  20. * message : Indicates whether the date is magic or not
