# Coffee-2a) Modify the nested loop example given. # Depending on the customer's selection, add a value # into a customer sub total. To keep it simple, assume # that they'll enter 1, 2, 3, 4 or 0. If they enter # 1, 2, 3, or 4, add that same number into their sub total 6 # (e.g. if choice is 1, subtotal + 1, 1f choice is 2, 7 # subtotal + 2 etc.). If they enter 0, that will indicate # they are done and the inner loop should break. 10 11 # coffee-2b) Add a grand total for the store into the 12 , # code from 2a.
