Following table summaries the rules for precedence and associativity of all operators, including those that we have not yet discussed. Operators on the same row have the same precedence; rows are in order of decreasing precedence, so, for example, *, /, and % all have the same precedence, which is higher than that of binary + and -. The operator () refers to function call. The operators -> and . are used to access members of structures;
| OPERATORS | ASSOCIATIVITY | |
|---|---|---|
| Function Expression | () | Left to Right |
| Array Expression | [] | Left to Right |
| Structure Operator | -> | Left to Right |
| Structure Operator | . | Left to Right |
| Unary minus | - | Right to Left |
| Increment/Decrement | ++, -- | Right to Left |
| One’s compliment | ~ | Right to Left |
| Negation | ! | Right to Left |
| Address of | & | Right to Left |
| Value of address | `*` | Right to Left |
| Type cast | (type) | Right to Left |
| Size in bytes | sizeof | Right to Left |
| Multiplication | `*` | Left to Right |
| Division | / | Left to Right |
| Modulus | % | Left to Right |
| Addition | + | Left to Right |
| Subtraction | - | Left to Right |
| Left shift | << | Left to Right |
| Right shift | >> | Left to Right |
| Less than | < | Left to Right |
| Less than or equal to | <= | Left to Right |
| Greater than | > | Left to Right |
| Greater than or equal to | >= | Left to Right |
| Equal to | == | Left to Right |
| Not equal to | != | Left to Right |
| Bitwise AND | & | Left to Right |
| Bitwise exclusive OR | ^ | Left to Right |
| Bitwise inclusive OR | | | Left to Right |
| Logical AND | && | Left to Right |
| Logical OR | || | Left to Right |
| Conditional | ?: | Right to Left |
| Assignment | =, *=, /=, %=, +=, -=, &=, ^=, |=, <<=, >>= | Right to Left |
| Comma | , | Right to Left |
Unary & +, -, and * have higher precedence than the binary forms.
