I want to modify this c programming codes to use arrays to keep track of up to 5 customer selections and prices by using arrays instead of atomic variables wherever necessary. You will be passing arrays to your functions and also incorporating loops to get user selections etc. You will still offer the BOGO if they buy 2 items and a Get the Cheapest Item Free sale if they buy 3 or more items.

could you make these modifications inside the following codes?
