Precedence and binding of operators

Priority Level	operator	name or meaning	Use Form	Combining Direction	Description
1	Post + +	Post Self-add operator	Variable name + +	Left to right
Post--	Back-up self-subtraction operators	Variable name--
[ ]	Array subscript	array name [INT-expression]
( )	Parentheses	(expression)/function name (formal parameter list)
.	Member selection (object)	Object. Member name
->	Member selection (pointers)	Object pointer-> member name
2	-	Minus sign operator	-An expression	Right to Left	Monocular operator
Type	Force type conversions	(data type) expression
Predecessor + +	Forward self-add operator	+ + variable Name	Monocular operator
Predecessor--	Forward self-subtraction operator	--Variable name	Monocular operator
*	Value operator	* Pointer expression	Monocular operator
&	Take address operator	& Left-Value expression	Monocular operator
!	Logical non-operator	! An expression	Monocular operator
~	Bitwise inverse operator	~ Expression	Monocular operator
sizeof	Length operator	sizeof expression/sizeof (type)
3	/	Except	An expression/expression	Left to right	Binocular operator
*	By	Expression * Expression	Binocular operator
%	Remainder (modulo)	Integral expression% integer expression	Binocular operator
4	+	Add	expression + expression	Left to right	Binocular operator
-	Reducing	Expression-An expression	Binocular operator
5	<<	Move left	Expressions << Expressions	Left to right	Binocular operator
>>	Move right	Expressions >> Expressions	Binocular operator
6	>	Greater than	Expressions > expressions	Left to right	Binocular operator
>=	Greater than or equal to	Expression >= An expression	Binocular operator
<	Less than	Expressions < expressions	Binocular operator
<=	Less than or equal to	Expression <= An expression	Binocular operator
7	==	Equals	expression = = Expression	Left to right	Binocular operator
!=	Not equal to	Expression!= An expression	Binocular operator
8	&	Bitwise AND	Integral Expressions & Integer expressions	Left to right	Binocular operator
9	^	Per-bitwise XOR OR	Integral expression ^ integral expression	Left to right	Binocular operator
Ten	|	by bit or	Integral expression | Integral expression	Left to right	Binocular operator
One	&&	Logic and	Expressions && Expressions	Left to right	Binocular operator
of	||	Logical OR	expression | | An expression	Left to right	Binocular operator
of	?:	Conditional operator	Expression 1-expression 2: Expression 3	Right to Left	Three-mesh operator
-	=	Assignment operator	variable = expression	Right to Left
/=	Assign value in addition to	Variable/= expression
*=	After multiplication assign value	Variable *= expression
%=	To assign a value after taking a model	Variable%= expression
+=	Add and then assign value	Variable = = Expression
-=	After minus assignment	Variable-= expression
<<=	Assign values after left shift	Variable <<= expression
>>=	Assign value after right shift	Variable >>= expression
&=	Bitwise AND Post-assignment	Variable &= expression
^=	Assign values by bitwise OR after	Variable ^= expression
|=	Bitwise OR post-value assignment	Variable |= expression
-	,	Comma operator	expressions, Expressions,...	Left to right	Order from left to right

* Priority one column number smaller priority greater
