Alice has hired you to improve some code used at the restaurant. The code we’ll be improving on is shown below.
Read through the code line-by-line with your partner before writing down your observations in the tables below.
# cost :: String -> Number
# given a item, produce the cost of that item
fun cost(item):
ask:
| item == "hamburger" then: 6.0
| item == "onion rings" then: 3.5
| item == "fried tofu" then: 5.25
| item == "pie" then: 2.25
| otherwise: "Sorry, that’s not on the menu!"
end
end
