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

Kotlin – Odd Number Program

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

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

n % 2 == 0

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


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


fun main() {
    print("Enter an integer : ")
    val n = readLine()!!.toInt()
    if (n % 2 == 1) {
        println("$n is odd.")
    } else {
        println("$n is not odd.")

Output #1

Enter an integer : 7
7 is odd.

Output #2

Enter an integer : 8
8 is not odd.
