For each of the following, write C++ statements that perform the specified task. Assume that double-precision, floating-point numbers are stored in eight bytes and that the starting address of the built-in array is at location 1002500 in memory. Each part of the exercise should use the re- sults of previous parts where appropriate.

a) Use a for statement to display the elements of built-in array numbers using pointer/off- set notation with the built-in array’s name as the pointer. b) Use a for statement to display the elements of built-in array numbers using pointer/sub- script notation with pointer nPtr. c) Refer to the fourth element of built-in array numbers using array subscript notation, pointer/offset notation with the built-in array’s name as the pointer, pointer subscript notation with nPtr and pointer/offset notation with nPtr. d) Assuming that nPtr points to the beginning of built-in array numbers, what address is referenced by nPtr + 8? What value is stored at that location? e) Assuming that nPtr points to numbers[5], what address is referenced by nPtr after nPtr -= 4 is executed? What’s the value stored at that location?
