11. class Date implementation

• The implementation of Date class uses previously defined serial date conversion functions:

  
      #include <iostream>
  
      int serial_julian_date( int Month, int Day, int Year );
      int serial_2_month( int nDate );
      int serial_2_day( int nDate );
      int serial_2_year( int nDate );
  
      class Date {
          // member variables
          int serial_date;
      public:
          // member functions
          void set_date( int month, int day, int year );
          int get_month();
          int get_day();
          int get_year();
      };
