Kotlin Program to Convert Octal Number to Decimal and vice-versa

fun main(args: Array<String>) {
    val decimal = 78
    val octal = convertDecimalToOctal(decimal)
    println("$decimal in decimal = $octal in octal")
}

fun convertDecimalToOctal(decimal: Int): Int {
    var decimal = decimal
    var octalNumber = 0
    var i = 1

    while (decimal != 0) {
        octalNumber += decimal % 8 * i
        decimal /= 8
        i *= 10
    }

    return octalNumber
}
 

Output:

78 in decimal = 116 in octal
