Use a user defined function and appropriate conditional and looping statements to create a program using c++ compiler that will:

(a) ask the item price from the user

(b) ask how many items to purchase for a specific item price

(c) ask if there are other items to purchase, if yes, repeat the first step, proceed to the next step if otherwise

(d) compute and display for the total amount to pay

(e) ask for the payment from the user

(f) accepts only enough amount of payment, ask another payment if otherwise

(g) compute and display change
