C-language operator precedence

First level (4, from left to right): [] array subscript, () parentheses,. Member selection (object), member selection (pointer)

Second level (9, right-to-left union):-Minus sign operator, (type) coercion type conversion, + + increment operator 、--decrement operator, * accessor operator, & take address operator,! Logical non-operator, ~ bitwise negation operator.

Level Three (3, from left to right):/Except, * Multiply,% take modulo

Level fourth (2, combined from left to right): + Plus,-minus

Fifth level (2, combined from left to right):<< left shift,>> right shift

Sixth level (4, from left to right):> greater than, >= greater than or equal to,< less than, <= less than or equal to

Level seventh (2, from left to right): = = equals,! = is not equal to

Level eighth (one, from left to right):& bitwise AND

Level Nineth (one, left to right combination): ^ Bitwise XOR

Level tenth (one, from left to right): | Bitwise OR

Level 11th (one, from left to right):&& logic and

Level 12th (one, from left to right): | | Logical OR

Level 13th (one, from left to right):?: conditional operator

14th level (12, from left to right): = assignment operator,/= after assignment, *= multiply,%= modulus assignment, + = plus assignment,-= minus assignment, <<= left shift assignment, >>= right Shift assignment, &= bitwise and post assignment, ^= bitwise XOR or post-assignment, |= bitwise OR post-assignment, |= bitwise OR post-assigned value

Level 15th (one, left to right):, comma operator
