The address 0 is generally considered unusable T True or False! T True or False!Ī pointer variable that has not been initialized is called a null pointer. The new operator dynamically allocates memory. When used as function parameters, reference variables are much easier to work with than pointers. Pointers may be compared using the relational operators. F True or False!Īny mathematical operation, including multiplication and division, may be performed on a pointer. You can change the address that an array name points to. The address operator is not needed to assign an array's address to a pointer. 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. When the indirection operator is used with a pointer variable, you are actually working with the value the pointer is pointing to T True or False!Īrray names cannot be de-referenced with the indirection operator. The & operator de-references a pointer F True or False! The & symbol is called the indirection operator. Pointer variables are designed to hold addresses. ![]() The * operator is used to get the address of a variable. New True or False!Įach byte of memory is assigned a unique address. Delete You should only use pointers with delete that were previously used with _. Null Pointer When a program is finished with a chunk of dynamically allocated memory, it should free it with the _ operator. Address 0 or Null A pointer that contains the address 0 is called a _ pointer. New Operator Under older compilers, if the new operator cannot allocate the amount of memory requested it returns _. ![]() Memory allocation The _ operator is used to dynamically allocate memory. Pointers Creating variables while a program is running is called _. * Array names can be used as _, and vice versa. Pointer The _ operator can be used to work with the variable a pointer points to. & _ variables are designed to hold addresses. ![]() Address The _ operator can be used to determine a variable's address. Each byte in memory is assigned a unique _. What are two advantages of declaring a pointer parameter as a constant pointer? Declaring a pointer parameter as a constant specify the function can't change what it points to and we can't use to change contents of arguments. What is the difference between a pointer to a constant and a constant pointer? A pointer to constant may not be used to change the value it points to.
