Question

Using the below program as a starting point

C++ Program - Arrays- Chapter 9

    Include the following header files in your program:     string, iomanip, iostream
Suggestion: code steps 1 thru 4 then test then add requirement 5, then test, then add 6, then test etc. Add comments to display assignment //step 1., //step 2. etc. This program is to have no programer created functions. Just do everything in main and make sure you comment each step so I can grade more easily.
C++ Program Pointers
Before starting on this project you should make sure points 1 to 15 are working properly from Chapter 7 Arrays project.
This program is to have no programer created functions. Just do everything in main and make sure you comment each step so I can grade more easily.
C++ Program Extension - This will be graded as a separate program but will add the following to Chapter 7 Arrays project. Don't forget to include comments with the corresponding number.

Extend the Array project to include:
16. Define a pointer to a double, pdArray.
17. Assign the pointer, pdArray, to contain the address of the double array, dArr:
18. Use the array name, dArr, to print out the array elements with subscript notation, [ ]. All on 1 line a space between each.
19. Use the pointer to print out the array elements with pointer notation while not changing the pointer itself. Use a for loop. *( pdArray + Cnt1) would be an example. All on 1 line a space between each.
20. Use the pointer to print out the array elements with pointer notation but change the pointer to point to the actual array element rather than the method in 18. All on 1 line.
*pdArray would do this if the loop has the following post loop operation:   pdArray++
21. Use the array name for the double array and pointer notation to print the entire array, all on one line.
22. Using a different pointer, piArray, allocate enough memory for 100 int's and assign the address to the pointer.
23. In a for loop assign every item in the array to be a random number from 1 to 49 ( hint: rand() % 6 + 1 gives random numbers from 1 to 6 )
24. Using cout print the first 10 items in the array, all on 1 line.
