Appendix C. Operator Precedence

It is important to understand that operators have a precedence, but it is not essential to memorize the precedence.

Precedence is the order in which a program performs the operations in a formula. If one operator has precedence over another operator, it is evaluated first.

Higher precedence operators “bind tighter” than lower precedence operators; thus, higher precedence operators are evaluated first. The lower an operator’s rank in Table C.1, the higher its precedence.

Table C.1. The Precedence of Operators

Rank	Name	Operator
1	Scope resolution	::
2	Member selection, subscripting, function calls, postfix increment and decrement	. ->
		()
		++ --
3	Sizeof, prefix increment and decrement, complement, and, not, unary minus and plus, ...
