/*  Olympics.cs  (c) 2003 Kari Laitinen

    This program demonstrates the use of an array of
    objects, or, more precisely, an array that contains
    references to objects. The program first introduces
    a class named Olympics. An Olympics object can contain
    the data of olympic games. By using the class Olympics,
    an array named olympics_table is defined inside
    the Main() method of class named OlympicsDataFinder.
    olympics_table is used to search data of olympic games.
