Notation in Expressions
The C++ language specifies certain compatibilities when specifying operands. The following table shows the types of operands acceptable to operators that require operands of type type.
Operand Types Acceptable to Operators
Type expected |
Types allowed |
|---|---|

const type volatile type type& const type& volatile type& volatile const type volatile const type& |
type* |
type* consttype* volatiletype* volatile const |
const type |
typeconst typeconst type& |
volatile type |
typevolatile typevolatile type& |
Because the preceding rules can always be used in combination, a const pointer to a volatile object can be supplied where a pointer is expected.
