C++ (please add comments)

Program 4)

Modify the main() function in the following program to add a Bathroom of size (10.2, 10.5) and

existing Dining room is now modified to be 10.6, 8.0 instead of 14,10.5

Add comments where you are adding or modifying the code

Your program should display Total area of the home after the changes.

Extra points:

Add functionality so you can enter the price per square feet as a public variable.

Then you add new code to calculate price of each Room and total price of the house.
