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:

Unary 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;
