Kotlin – Average of numbers

In this tutorial, you shall learn how to write a program to find the average of numbers given in an array in Kotlin.

Kotlin – Average of Numbers Program

To find the average of multiple numbers given in an array in Kotlin, find the sum of the given numbers and then divide the sum by the count of numbers given.

Program

In the following program, we take an array of numbers in numsArray, then find the average of the numbers in the array.

Main.kt

fun main() {
    val numsArray = arrayOf(4, 0, 5, 2, 10, 3, 8)

    var sum = 0
    for (num in numsArray) {
        sum += num
    }

    val avg = sum.toDouble() / numsArray.size
    println("Average : $avg.")
}

Output #1

Average : 4.571428571428571.
