Operators in C language and their priority

Priority	Operator	Name or meaning	Usage	Integration direction	Description
1	[]	Array subscript	Array name [constant expression]	Left to right
	()	Parentheses	(Expression)/function name (parameter table)
	.	Member selection (object)	Object. member name
	->	Member selection (pointer)	Object Pointer-> member name
2	-	Negative Operator	-Expression	Right to left	Single Object Operator
	(Type)	Forced type conversion	(Data Type) Expression
	++	Auto-increment operator	++ Variable name/variable name ++		Single Object Operator
	--	Auto-subtraction Operator	-- Variable name/variable name --		Single Object Operator
	*	Value Operator	* Pointer variable		Single Object Operator
	&	Bitwise operators	& Variable name		Single Object Operator
	!	Logical non-Operator	! Expression		Single Object Operator
	~	Bitwise Inverse Operator	~ Expression		Single Object Operator
	Sizeof	Length Operator	Sizeof (expression)
3	/	Division	Expressions/Expressions	Left to right	Binary Operators
	*	Multiplication	Expression * Expression		Binary Operators
	%	Remainder (Modulo)	Integer expression/Integer expression		Binary Operators
4	+	Add	Expression + expression	Left to right	Binary Operators
	-	Subtraction	Expression-expression		Binary Operators
5	<	Move left	Variable <expression	Left to right	Binary Operators
	>	Right Shift	Variable> Expression		Binary Operators
6	>	Greater	Expression> Expression	Left to right	Binary Operators
	> =	Greater than or equal	Expression> = expression		Binary Operators
	<	Less	Expression <expression		Binary Operators
	<=	Less than or equal	Expression <= expression		Binary Operators
7	=	Equal	Expression = expression	Left to right	Binary Operators
	! =	Not equal	Expression! = Expression		Binary Operators
8	&	Bitwise AND	Expressions & Expressions	Left to right	Binary Operators
9	^	Bitwise OR	Expression ^ expression	Left to right	Binary Operators
10	|	By bit or	Expression | expression	Left to right	Binary Operators
11	&&	Logic and	Expressions & Expressions	Left to right	Binary Operators
12	|	Logic or	Expression | expression	Left to right	Binary Operators
13	? :	Conditional Operators	Expression 1? Expression 2: expression 3	Right to left	Three-object Operator
14	=	Value assignment operator	Variable = expression	Right to left
	/=	Assignment After Division	Variable/= expression
	* =	Assign value after Multiplication	Variable * = expression
	% =	Assign value after modulo operation	Variable % = expression
	+ =	Add and assign values	Variable + = expression
	-=	Value after subtraction	Variable-= expression
	<=	Value after left shift	Variable <= expression
	>>=	Value after right shift	Variable> = expression
	& =	Bitwise AND postvalue	Variable & = expression
	^ =	Value Based on bitwise XOR	Variable ^ = expression
	| =	Value by bit or after	Variable | = expression
15	,	Comma Operator	Expressions, expressions ,...	Left to right	Sequential operation from left to right

Note:

For operators with the same priority, the operation order is determined by the combination direction.
