// Use the return value from AreaPerPerson().

class BuildingDemo {

  static void Main() {

    Building house = new Building();

    Building office = new Building();

    int areaPP; // area per person

    // Assign values to fields in house.

    house.Occupants = 4;

    house.Area = 2500;

    house.Floors = 2;

    // Assign values to fields in office.

    office.Occupants = 25;

    office.Area = 4200;

    office.Floors = 3;

    // Obtain area per person for house.

    areaPP = house.AreaPerPerson();

    Console.WriteLine("house has:\n  " +

                      house.Floors + " floors\n  " +

                      house.Occupants + " occupants\n  " +

                      house.Area + " total area\n  " +

                      areaPP + " area per person");

    Console.WriteLine();

    // Obtain area per person for office.

    areaPP = office.AreaPerPerson();

    Console.WriteLine("office has:\n  " +

                      office.Floors + " floors\n  " +

                      office.Occupants + " occupants\n  " +

                      office.Area + " total area\n  " +

                      areaPP + " area per person");

  }

}

The output is the same as shown earlier.
