Where is the mistake in my code? #Kotlin

Question

Outputs result when any input is given.

fun main(args: Array<String>) {
var age = readLine()!!.toInt()
var result = when{
age >=0 && age <=11->"Child"
age >=12 && age <=17->"Teen"
age >=18 && age <=64->"Adult"
else -> "Senior"
}
println("result")
}

Answer 1

println(result)

Answer 2

A should be lowercase in age

Answer 3

doesn't well know kotlin (and not aware of 'when' construct statement), but if you want to print the value stored in 'result', then remove the quotes:

print(result)

Answer 4

Thanks both of you,,. Still one case is not solved.

Given an age as input, you need to output the age group according to the following categories:
Child: 0 - 11
Teen: 12 - 17
Adult: 18 - 64
Senior: 65+

In case the age is negative, you need to output "Invalid age".

Sample Input:
42

Sample Output:
Adult

Answer 5

what is the task description?

Answer 6

Ok I am trying ..the negative part missed.

Answer 7

Still showing error in one part.

fun main(args: Array<String>) {
var age = readLine()!!.toInt()
var result = when{
age >=0 && age <=11->"Child"
age >=12 && age <=17->"Teen"
age >=18 && age <=64->"Adult"
age<0->"Invalid Age"
else->"Senior"
}
println(result)
}

Answer 8

fun main(args: Array<String>) {
var age = readLine()!!.toInt()
val result = when{
age >=0 && age <=11->"Child"
age >=12 && age <=17->"Teen"
age >=18 && age <=64->"Adult"
age > 65 ->"Senior"
else->"Invalid age"
}
println(result)
}

Change var to val
