Return: Quiz III in Kotlin

Quiz: What would this code produce if we were to copy-paste it in a code editor and run it?

fun get_greeting(name: String): String {
	println("Hey, " + name)
}

fun mainFunction() {
	val greeting: String = get_greeting("Andy")
	println(greeting)
}

Important Note:

Do not use an actual code editor to get the answer! It would defy the whole purpose of the quiz!
