Why doesn't my code work correctly?

Question

My code is:
fun main(args: Array<String>) {
var age = 17
while (age <= 17) {
println("Hello")
age++
}
}
Why does Hello appear only once and not 17 times?

Answer 1

In the beginning age = 17, so age =< 17 is true because 17 is smaller or equal to 17.

The 2nd time age = 18, so age <= 17 is false because 18 is not smaller or equal to 17.

Answer 2

second time age =18 because of ”age++”
