CSCE Chapter 9
F
(T/F) A pointer variable that has not been initialized is called a null pointer.
F
(T/F) Any mathematical operation, including multiplication and division, may be performed on a pointer.
T
(T/F) Array names cannot be dereferenced with the indirection operator.
T
(T/F) Each byte of memory is assigned a unique address.
F
(T/F) In using pointer with the delete operator, it is not necessary for the pointer to have been previously used with the new operator.
T
(T/F) Pointer variables are designed to hold addresses.
T
(T/F) Pointers may be compared using the relation operators.
F
(T/F) The & operator dereferences a pointer.
F
(T/F) The & symbol is called the indirection operator.
F
(T/F) The * (indirection) operator is used to get the address of a variable.
T
(T/F) The address 0 is generally considered unusable.
T
(T/F) The address operator is not needed to assign an array's address to a pointer.
T
(T/F) The new operator dynamically allocates memory.
T
(T/F) When the indirection operator is used with a pointer variable, you are actually working with the value the pointer is pointing to.
T
(T/F) When used as function parameters, reference variables are much easier to work with than pointers.
T
(T/F) When you add a value to a pointer, you are actually adding that number times the size of the data type referenced by the pointer.
T
(T/F) You can change the address that an array name points to.
null
A pointer that contains the address 0 is call a(n) ___ pointer.
Pointers
Array names can be used as ___, and vice versa.
Ampersand
The ___ operator can be used to determine a variable's address.
Indirection (*)
The ___ operator can be used to work with the variable a pointer points to.
new
The ___ operator is used to dynamically allocate memory.
null
Under older compilers, if the new operator cannot allocate the amount of memory requested, it returns ___.
delete
When a program is finished with a chunk of dynamically allocated memory, it should free it with the ___ operator.
new
You should only use pointers with delete that were previously used with ___.
Pointer
___ variables are designed to hold addresses.
Dynamic Memory Allocation
Creating variables while a program is running is called ___.
Address
Each byte in memory is assigned a unique ___.
