What is the precedence of operators in C language?

The priority of operators in C language has the following rules: for operators of the same priority, the order of operations is determined by the direction of combination. That is, logical non-greater than arithmetic operator greater than relational operator greater than logical AND greater than logical or greater than assignment operator

This article mainly provides a detailed analysis and introduction to the priority of operators in C language. It has It has certain reference value and I hope it will be helpful to everyone.

Priority	Operator	Name or meaning	Use form	Combined direction	Instructions
1	[]	Array subscript	Array name[ Constant expression]	left to right	--
	()	##Parentheses	(expression)/function name(parameter list)		--
	.	Member selection (object)	Object.Member name		--
	##&	Get address operator	&Variable name
	!	Logical NOT operator	!Expression
	(Type)	Forced type conversion	(Data type)Expression Formula		--
##/	except	Expression/expression	Left to right	Binary operator
	Multiply	expression*expression
	Remainder (modulo)	##Integer expression% Integer expression

The simple note is:! > Arithmetic operators > Relational operators > && > || > Assignment operators
