The operand of the unary indirection operator (*)
must be a pointer to type T. The resulting type is T. If type T
is not a function type, the unary-expression
is an lvalue.
The contents of pointers are memory addresses. No range checking
is done on indirection operations. Specifically, storing values
indirectly through a pointer that was not correctly initialized
can cause bounds errors or destruction of valid data.
The operand of the unary address-of operator (&)
must be a function designator or an lvalue. This precludes taking
the address of constants (for example, &3),
because 3 is
not an lvalue. If the type of the operand is T, the result of the
address of operator is a pointer to type T. The &
operator may not be applied to bit fields or objects with the register
storage class.
It is always true that if E
is an lvalue, then *&E
is an lvalue expression equal to E.
