Kotlin program using functions to display Armstrong numbers between intervals

Comprehensive Collection of Kotlin Examples

In this program, you will learn to use Kotlin functions to display all Armstrong numbers between two given intervals (low and high).

To find all Armstrong numbers between two integers, the function checkArmstrong() will be created. This functionCheck if a number is an Armstrong number.

Example: Armstrong numbers between two integers

fun main(args: Array<String>) {
　　　　val low =　999
　　　　val high =　99999
　　　　for (number in low　+　1..high　-　1) {
　　　　　　　　if (checkArmstrong(number))
　　　　　　　　　　　　print("$number ")
　　　　}
}
fun checkArmstrong(num: Int): Boolean {
　　　　var digits = 0
　　　　var result = 0
　　　　var originalNumber = num
　　　　//Digit Calculation
　　　　while (originalNumber != 0) {
　　　　　　　　originalNumber　/=　10
　　　　　　　　++digits
　　　　}
　　　　originalNumber = num
　　　　//The result includes the n-th power of its digits
　　　　while (originalNumber != 0) {
　　　　　　　　val remainder = originalNumber %　10
　　　　　　　　result　+The result is obtained by taking the n-th power of the digits and converting it to an integer.
　　　　　　　　originalNumber　/=　10
　　　　}
　　　　if (result == num)
　　　　　　　　return true
　　　　return false
}

When the program is run, the output is:

1634　8208　9474　54748　92727　93084

In the above program, we created a function named checkArmstrong(), which accepts a parameter num and returns a boolean value.

If the number isArmstrongif it returns true. Otherwise, it returns false.

According to the return value, the number will be printed on the screen within the main() function.

This is the equivalent Java code:Check Using FunctionArmstrongJava Program for Numbers.
