Challenge 1: Default Parameters & Named Arguments — Solution

fun orderPizza(size: String = "medium", toppings: Int = 1, extraCheese: Boolean = false) {
    println("Order: $size pizza, $toppings topping(s), extra cheese: $extraCheese")
}

fun main() {
    orderPizza()
    orderPizza(size = "large")
    orderPizza(extraCheese = true)
    orderPizza("small", 3, true)
}

/*
Output:
Order: medium pizza, 1 topping(s), extra cheese: false
Order: large pizza, 1 topping(s), extra cheese: false
Order: medium pizza, 1 topping(s), extra cheese: true
Order: small pizza, 3 topping(s), extra cheese: true

Notes:
- orderPizza() uses all three defaults.
- orderPizza(size = "large") overrides just size by name; toppings and
  extraCheese still use their defaults.
- orderPizza(extraCheese = true) skips straight to the third parameter by
  name, without needing to also specify size or toppings.
- orderPizza("small", 3, true) supplies all three positionally, in order.
