Kotlin Function: Print numbers from 1 to n, Return Unit

Kotlin Function: Exercise-12 with Solution

Write a Kotlin function that takes an integer n as an argument and prints the numbers from 1 to n on separate lines. The function should return Unit.

Sample Solution:

Kotlin Code:

fun printNumbers(n: Int): Unit {
    for (i in 1..n) {
        println(i)
    }
}

fun main() {
    val number = 7
    printNumbers(number)
}

Sample Output:

1
2
3
4
5
6
7

Explanation:

The "printNumbers()" function receives an n parameter of type Int. It uses a for loop to iterate from 1 to n and prints each number on a separate line using the println function. The return type Unit indicates that the function doesn't explicitly return a value.

In the "main()" function, a sample number (number) is provided, and printNumbers is called with this number as an argument. The function then prints the numbers from 1 to number on separate lines.

Previous: Print a greeting message with person's name.
Next: Print even numbers from list, Return Unit.
