NOTE: See also the general page on C Programming.

The follow is the order of precedence, from highest to lowest, for the C programming language:

Operator Associativity

(expr) [index] -> . Left ==> Right

! ~ ++ -- (type) sizeof
Unary operator: + - * & Right <== Left

* / % Left ==> Right

+ - Left ==> Right

<< >> Left ==> right

< <= > >= Left ==> Right

== != Left ==> Right

Binary operator: & Left ==> Right

Binary operator: ^ Left ==> Right

Binary operator: | Left ==> Right

&& Left ==> Right

|| Left ==> Right

expr ? true_expr : false_expr Right <== Left

+= -= *= /= <<=
&= ^= |= %= >>= = Right <== Left

, Left ==> Right

Unary operator:

Operator Example

+ +23209

- -value

* *pointer

& &variable

Binary operator :

Binary
Operator Example

& t = 0xCC; p = 0xAA;
(t & p) == 0x88;

^ r = 0xF0; w = 0xCC;
(r ^ w) == 0x3C;

| x = 0x99; y = 0x96;
(x | y) == 0x9F;
