5,088 Pointsfor coin in coins
Why is coin.rawvalue used and not Coin.rawvalue? How does coin have any values assigned to it?
enum Coin: Double {
case penny = 0.01
case nickel = 0.05
case dime = 0.1
case quarter = 0.25
}
let coins: [Coin] = [.penny, .nickel, .dime, .dime, .quarter, .quarter, .quarter]
func sum(having coins: [Coin]) -> Double {
var total: Double = 0
for coin in coins {
total += coin.rawValue
}
return total
}
sum(having: coins)
