Expressions and Operators
Types of Expressions
This table lists the C and C++ language operators in order of precedence and shows the direction of associativity for each operator. In C++, the primary scope resolution operator (::) has the highest precedence, followed by the other primary operators. In C, because there is no scope resolution operator, the other primary operators have the highest precedence. The comma operator has the lowest precedence. Operators that appear in the same group have the same precedence.
| Operator Name | Associativity | Operators |
|---|---|---|
| Primary scope resolution | left to right | :: |
| Primary | left to right | () [ ] . -> dynamic_cast typeid |
| Unary | right to left | ++ -- + - ! ~ & * (type_name) sizeof new delete |
| C++ Pointer to Member | left to right | .*->* |
| Multiplicative | left to right | * / % |
| Additive | left to right | + - |
| Bitwise Shift | left to right | << >> |
| Relational | left to right | < > <= >= |
| Equality | 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 | = += -= *= /= <<= >>= %= &= ^= |= |
