Kotlin Do While Loop

Chapter: Kotlin Last Updated: 19-11-2017 14:02:49 UTC

Program:

            /* ............... START ............... */
                
fun main(args: Array<String>) {

    var sum: Int = 0
    var input: String

    do {
        print("Enter an integer: ")
        input = readLine()!!
        sum += input.toInt()

    } while (input != "0")

    println("Sum = $sum")
}

                /* ............... END ............... */
        

Output

Enter an integer: 3
Enter an integer: 5
Enter an integer: 7
Enter an integer: 8
Enter an integer: 0
Sum = 23

Notes:

• do..while loop in Kotlin guarantees at least one execution of block of statements because loop evaluates the boolean expression at the end of the loop’s body.
• Here the above program user input are taking by using readline() function inside the do while loop.
• While loop outside the body of do will check whether the condition is true or not and iterate accordingly.
• It will exits the loop when the while statement statement condition is false.
