Precedence and Associativity of Operators

From <The C Programming Language>(p.53)
 

OPERATORS	ASSOCIATIVITY
( )    [ ]    ->    .	Left to right
!  ~  ++  --  +  -  *  &  ( type ) sizeof	Right to left
*    /    %	Left to right
+    -	Left to right
<<    >>	Left to right
<    <=    >    >=	Left to right
==    !=	Left to right
&	Left to right
^	Left to right
|	Left to right
&&	Left to right
||	Left to right
=  +=  -=  *=  /=  %=  &=  ^=  |=  <<=  >>=	Right to left
?:	Right to left
,	Left to right

　　Unary &, +, -, and * have higher precedence than the binary forms.
