C# 0 The Complete Reference

AreaPerPerson( )

method, itself. The first line of 

AreaPerPerson( )

 is

public void AreaPerPerson() {

This line declares a method called 

AreaPerPerson

 that has no parameters. It is specified as 

public

, so it can be used by all other parts of the program. Its return type is 

void

. Thus, 

AreaPerPerson( )

 does not return a value to the caller. The line ends with the opening curly 

brace of the method body.

The body of 

AreaPerPerson( )

 consists solely of this statement:

Console.WriteLine("  " + Area / Occupants + " area per person");

This statement displays the area-per-person of a building by dividing 

Area

 by 

Occupants

.

Since each object of type 

Building

 has its own copy of 

Area

 and 

Occupants

, when 

AreaPerPerson( )

 is called, the computation uses the calling object’s copies of those 

variables.

The

AreaPerPerson( )

 method ends when its closing curly brace is encountered. This 

causes program control to transfer back to the caller.
