Section II—C Operators
C is rich in operators. Table RS.I.1 lists the C operators in order of decreasing precedence and indicates how they associate. All operators are binary (two operands) unless otherwise indicated. Note that some binary and unary operators, such as * (multiplication) and * (indirection), share the same symbol but have different precedence. Following the table are summaries of each operator.
| Operators (from high to low precedence) | Associativity |
|---|---|
| ++ (postfix) — (postfix)( ) [ ] . > | L–R |
|
++ (prefix) — (prefix) - + ~ !
sizeof * (dereference) & (address) (type) (all unary) | R-L |
| * / % | L–R |
| + - (both binary) | L–R |
| << >> | L–R |
| < > <= >= | L–R |
| == != | L–R |
| & | L–R |
| ^ | L–R |
| | | L–R |
| && | L–R |
| || | L–R |
| ? : (conditional expression) ... |
