Appendix B. C OPERATORS

C is rich in operators. Table B.1 lists the C operators in order of decreasing precedence and indicates how they associate. All operators are binary (two operands) unless otherwise indicated. Note that some binary and unary operators, such as * (multiplication) and * (indirection), share the same symbol but have different precedence. Following the table are summaries of each operator.

Table  B.1. The C operators.

Operators (from high to low precedence)	Associativity
++ (postfix) -- (postfix) ( ) [ ] . ->	L-R
++ (prefix) -- (prefix) - + ~ !
sizeof * (dereference) & (address)
(type) (all unary)	R-L
* / %	L-R
+ - (both binary)	L-R
« >>	L-R
< > <= >=	L-R
== !=	L-R
&	L-R
^	L-R
	L-R
&&	L-R
	L-R
? : (conditional expression)	R-L
= *= /= %= += -= «= >>= &= = ^=	R-L
, (comma operator)	L-R
