C-language operator precedence

Priority level	Operator	Name or meaning	Use form	Combining direction	Description
1	[]	Array subscript	array name [constant expression]	Left to right
()	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
++	Self-increasing operator	+ + variable name/variable name + +	Monocular operator
--	Self-subtraction operators	--Variable name/variable name--	Monocular operator
*	Value operator	* Pointer variable	Monocular operator
&	Take address operator	& Variable Name	Monocular operator
!	Logical non-operator	! An expression	Monocular operator
~	Bitwise inverse operator	~ Expression	Monocular operator
sizeof	Length operator	sizeof (expression)
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	Variables << expressions	Left to right	Binocular operator
>>	Move right	Variables >> 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	Expressions & Expressions	Left to right	Binocular operator
9	^	Per-bitwise XOR OR	expression ^ expression	Left to right	Binocular operator
10	|	by bit or	Expressions-Expressions	Left to right	Binocular operator
11	&&	Logic and	Expressions && Expressions	Left to right	Binocular operator
12	||	Logical OR	expression | | An expression	Left to right	Binocular operator
13	?:	Conditional operator	Expression of 1? Expression 2: Expression 3	Right to Left	Three-mesh operator
14	=	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
15	,	Comma operator	expressions, Expressions,...	Left to right	Order from left to right

Description

operator of the same priority, the order of operations is determined by the binding direction.

The simple note is:. > Single-eye operator > Arithmetic operator > Relational operator > && > | | > Assignment Operators
