1. Your First Kotlin Program

[THEORY]

[PREDICT]

Read the code carefully before you run it.

prediction.kt

fun main() {
    println("Warehouse inventory starting.")
    print("Status: ")
    print("ready")
}

How many lines does this program print, and what is in each line?

[TASK]

Complete the program so that it prints exactly two lines: first Checkout system, then Version 2.3. Use only println for this.

task.kt

fun main() { // TODO: print two lines }

Before you get a hint: what have you tried, and where exactly are you stuck?

2. Where does execution of a Kotlin program begin?

In the top-level function main(), which needs no surrounding class In the first line of the file, as in a scripting language In the first function declared in the file, whatever it is called In the class that is named like the file, as in Java
