Priority of operators for C defects and traps

The operator priority is shown in the following table, which is reduced from left to right and from top to bottom.

() (Parentheses) [] (array subscript). (structure member)-> (pointer structure member) maximum limit
── ─ ┃ ↑
! (Non-logical). (bitwise inverse)-(negative) ++ (plus 1) -- (minus 1) & (variable address) │
── ─ ┃ │
* (Pointer content) type (function description) sizeof (length calculation) │
── ─ ┃ │
* (Multiplication)/(Division) % (Modulo) │
── ─ ┃ │
+ (Plus)-(minus) ┃ │
── ─ ┃ │
<(Shifted left)> (shifted right) │
── ─ ┃ │
<(Less than) <= (less than or equal to)> (greater than)> = (greater than or equal to) │
── ─ ┃ │
= (Equal )! = (Not equal to) sampled │
── ─ ┃ │
& (Bits and) bytes │
── ─ ┃ │
^ (Bitwise OR) │
── ─ ┃ │
| (Bit or) │
── ─ ┃ │
& (Logical and) │
── ─ ┃ │
| (Logical or) │
── ─ ┃ │
? :(? Expression) │
── ─ ┃ │
= + =-= (Joint Operation) │
── ─ ┃ │
, (Comma operator) the lowest limit
