C# 0 The Complete Reference

MaxOccupant( )

 is called, the parameter 

minArea

 receives the minimum space 

needed for each occupant. The method divides the total area of the building by this value 

and returns the result.

The entire 

Building

 class that includes 

MaxOccupant( )

 is shown here:

/*

   Add a parameterized method that computes the

   maximum number of people that can occupy a

   building assuming each needs a specified

   minimum space.

*/

using System;

class Building {

  public int Floors;    // number of floors

  public int Area;      // total square footage of building

  public int Occupants; // number of occupants

  // Return the area per person.

  public int AreaPerPerson() {

    return Area / Occupants;

  }

  // Return the maximum number of occupants if each

  // is to have at least the specified minimum area.

  public int MaxOccupant(int minArea) {

    return Area / minArea;

  }

}

// Use MaxOccupant().

class BuildingDemo {

  static void Main() {

    Building house = new Building();

    Building office = new Building();

    // Assign values to fields in house.

    house.Occupants = 4;

    house.Area = 2500;

    house.Floors = 2;

Maximum occupants for house if each has 300 square feet: 8

Maximum occupants for office if each has 300 square feet: 14
