Kotlin - Odd Number Program

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.

Program

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

Main.kt

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.

Conclusion

In this Kotlin Tutorial, we learned how to check if given number is odd number or not.
