Vending Machine Project
Your project will be a vending machine. Your machine will ask
the user to pick a choice of what they want to buy, input the money and
return the change to the user.
Your task is to complete the sections of the code that are marked
You already did an assignment to figure out the correct amount of change. However, the problem here is that you want to give back the correct change with the least amount of coins given what the vending machine has.
