c language operator precedence

An expression can contain multiple operators. In this case, the precedence of the operators determines which part of the expression is processed as the operand of each operator.

If two operands in an expression have the same priority, then their associativity determines They are combined from left to right or right to left.

The precedence and associativity of all C language operators:

##3 Type conversion operator: (type name) From right to left ##4 5 6 ##7 Relational operator:< <= >>= From left to right 8 Equality operator: == != Left to right 9 Bitwise operator AND: & Left to right 10 Bitwise operator XOR: ^ From left to right 11 Bitwise operator OR: | Left to right Logical operator AND: && Logical operator OR: || Conditional operator: ?: Assignment operator: = = -= *= /= %= &= <<= >>=

Priority	Operator		Associative Law
1	Suffix Operator: [] () · -> --(type name){list}		from left to right
2	Unary operators: -- ! ~ - - * & sizeof_Alignof		right to left
Multiplication and division operators: * / %	From left to right
Addition and subtraction operators: -	From left to right
Shift operator:<< >>	From left to right
			##12
Left to right			13
From left to right			14
Right to left			15
From right to left
16	Comma operator:,		From left to right
