Your challenge is to put together a vending machine knowing what you know about formatted output, input, selection and repetition.

Your vending machine will have the following:

a physical form using text / symbolic output to simulate an actual machine

top, bottom and sides represented

two across selections (so, 2 different pops next to one another per row)

descriptions of the selections and prices

the machine will accept change and bills up to $20, nothing larger, and make correct change

looping mechanism so the user can make as many selections as necessary

selection mechanism of your choice

good end user design evidenced by prompting that leads a user to a correct / complete interaction
