Write a program that tracks a drive through at Four Friends Fries
Have a queue for the line of cars
Have a stack of cooked fries for serving
Simulate 60 minutes worth of time at the drive thru.
Every minute, there is a 1/3 chance of a car showing up when a car gets to the front of the queue, it orders 1-6 orders of fries randomly the fry stack can have up to 8 fries at a time, track the 'time' they are done cooking. if a fry is older than 10 minutes, it can't be served you can be cooking up to 4 orders of fries at a time in the frier, they take 2 minutes to cook so for each 'minute' figure out if a new car a
ives in the drive through take any cooked fries out of the frier and add to the cooked fry stack ( with time done cooking ) take the order from the front car possibly add more fries to the frier to cook assume each order of fries costs $.5, and is sold for $1.
track total profit/loss after 60 minutes
