One of the accountant’s at Dunder Mifflin, Kevin Malone, investigates the option of obtaining a bank loan to help pay off his gambling debt
(https://www.youtube.com/watch?v=J1LvfXX9Uhs ). He tells the bank that he intends to use the loan to start an ice-cream business, called Malone’s Cones, which will sell delicious ice- cream such as Fudge the Magic Dragon. Kevin needs a simple program that keeps track of his monthly expenditure for the business so that he doesn’t accidently spend too much of the money – the balance at the end of the month should be either 0 or a positive value if he sells at least as much as he spends.
