Appendix B. C Operators
C is rich in operators. Table B.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) | R-L |
| = *= /= %= += -= ≪= >>= &= ... |
