📌 while Loop in Kotlin

In Kotlin, a while loop is used to execute a block of code repeatedly as long as the specified condition is true. It is generally used when the number of iterations is not known in advance.

✅ Syntax of while Loop

kotlin
var i = 1while (i <= 5) {    println("Iteration: $i")    i++ Iteration: 1Iteration: 2Iteration: 3Iteration: 4Iteration: 5

✅ Example 2: Infinite Loop (Avoid)

If the condition never becomes false, it results in an infinite loop.

kotlin
var i = 1while (true) {    println("This is loop number $i")    i++    import java.util.Scannerfun () {    val scanner = Scanner(System.`in`)    var number: Int    println("Enter a number greater than 0 (0 to exit): ")    number = scanner.nextInt()    while (number > 0) {        println("You entered: $number")        println(do {    // Code to execute} while (condition)

📌 Example:

kotlin
var count = 0do {    println("Count: $count")    count++} while (count < 3)

Output:

makefile
Count: 0Count: 1Count: 2

✅ Difference Between while and do-while

✅ Conclusion

• Use while if the loop might not execute at all.

• Use do-while when you need to ensure the loop runs at least once.

• Ensure you update variables inside the loop to avoid infinite loops.
