|
|
* Boolean data is one bit of information. True or false.
|
|
* It is common to use Booleans with control statements to
|
|
* determine the flow of a program. In this example, when the
|
|
* boolean value "x" is true, vertical black lines are drawn and when
|
|
* the boolean value "x" is false, horizontal gray lines are drawn.
