Type Boolean

Boolean is the simplest of all types.

Data of this type can only have one of two different values: true or false.

Data of the Boolean type originates as a result of tests that compare one thing with another:

• True or false, a penguin is taller than an ice skater?
• True or false, the hole in the ice is large enough for the penguin to dive through?
• True or false, this particular task has been performed the specified number of times?

You will learn more about data of type Boolean in future lessons that address selection and loop structures along with relational operators.
