Simple Program that allows you to decice what kind of hot beverage you'd like chosing between espresso/cappuccino/latte, keeps track of resources (water/milk/coffee), allows you to insert coins (quarters/dimes/nickles/pennies), gives you the change if the money inserted was enough and gives you the beverage you wanted! You can ask for a "report" to see the resources still available and the profit generated. Also with "off" you can shut down the machine.
