For each of the following, write C++ statements that perform the specified task. Assume that unsigned integers are stored in four bytes and that the starting address of the built-in array is at location 1002500 in memory.

Question

a) Use a for statement to display the elements of built-in array values using pointer/offset notation with the built-in array’s name as the pointer.
b) Use a for statement to display the elements of built-in array values by subscripting the pointer to the built-in array.
c) Refer to the fifth element of values using array subscript notation, pointer/offset notation with the built-in array name’s as the pointer, pointer subscript notation and point- er/offset notation.
d) What address is referenced by vPtr + 3? What value is stored at that location?
e) Assuming that vPtr points to values[4], what address is referenced by vPtr -= 4? What value is stored at that location?

Answer 1

```
a) for (int i{0}; i < SIZE; ++i) {
cout << setw(4) << *(values + i);
}
b) for (int i{0}; i < SIZE; ++i) {
cout << setw(4) << vPtr[i];
}
c) values[4], *(values + 4), vPtr[4], *(vPtr + 4)
d) The address of the location pertaining to values[3] (i.e., 1002506). 8.
e) The address of where values begins in memory (i.e., 1002500). 2.
