Kotlin Check if given number is even

In this tutorial, you shall learn how to write a program to check if given number is an even number in Kotlin.

Kotlin Even Number Program

To check if given number is even or not in Kotlin, divide the given number by 2 and check the remainder. If the remainder is zero, then the given number is an even number, else not.

If n is the given number, then the condition to check if n is even or not is

n % 2 == 0

The above expression returns true if n is even, or else it returns false.

Program

In the following program, we take a number in n, and check if it is even number or not using the above condition.

Main.kt

fun main() {
    print("Enter an integer : ")
    val n = readLine()!!.toInt()
    if (n % 2 == 0) {
        println("$n is even.")
    } else {
        println("$n is not even.")
    }
}

Output #1

Enter an integer : 8
8 is even.

Output #2

Enter an integer : 5
5 is not even.
