Boolean Expressions

1. Boolean Expressions

The if statements of the previous chapters asked simple true/false questions (boolean expressions) such as count<10. Often simple boolean expressions are not enough. This chapter discusses more complicated boolean expressions.

Boolean expressions have been prominent on past AP Computer Science tests.

Question 1:

You have decided to bake some cookies (much cheaper than buying them at the Mall).

An interesting cookie recipe calls for 4 cups of flour and 2 cups of sugar. You look in your pantry and
find 3 cups of flour and 2 cups of sugar.

Can you bake cookies with what you have?
