CHAPTER 40 — Boolean Expressions and
Short-circuit Operators

A boolean value (a true/false value) picks the branch of an if statement or allows a loop to continue. Sometimes a boolean expression is more complicated than we have seen so far in these notes. Often a program must make a decision based on a number of factors. This chapter will examine this topic and discuss some additional boolean operators.

Chapter Topics:

• Short-circuit && and || operators.
• Non-short-circuit & and | operators.
• Expressions made with several && operators.
• Expressions made with several || operators.
• Expressions made with mixed && and || operators.
• Precedence of && and || operators.
