Exam 10: Pointers

The advantage of using pointers rather than references is that the function call specifies that ____________________ are being used.

Pointers to functions are possible because function ____ are themselves pointer constants.

The C++ operator * means the address of .

As each variable is defined in a program, sufficient storage for it is assigned from a pool of computer memory locations made available to the compiler.

The ____________________ statement restores an allocated block of storage back to the free storage area (the heap) while a program is running.

References are used almost exclusively as formal function parameters and ____ types.

The ____ consists of unallocated memory that can be allocated to a program, as requested, while the program is running.

When an array is created, the compiler creates an internal point constant for it automatically and stores the array s ____ in this pointer.

The C++ ____ operator releases a block of bytes reserved previously.

If a character s address is stored in a pointer, only ____ byte(s) of storage would be retrieved when the address is used.

Access to multidimensional ____________________ can be made using pointer notation.

Like all variables, pointers can be initialized when they are ____________________.

Pointers must be ____________________ before they can be used to store an address.

The asterisk ( * ) symbol is also called the ____ operator.

In contrast to implicitly passing addresses with ____, addresses can be explicitly passed using pointers.

The addresses in pointers can be compared by using any of the C++ ____________________ operators.

To display the address of a variable, you can use C++ s address operator, ____.

Expressions taking the address of an array name are invalid because the pointer the compiler creates is ____________________ to the computer.

A double typically requires the retrieval of ____________________ bytes of storage.

A computer uses an array s ____ to calculate the array element s address based on both the array s starting address and the amount of storage each element uses.
