Kotlin Program: Print the first 10 natural numbers

Last update on August 27 2025 12:40:20 (UTC/GMT +8 hours)

Write a Kotlin program to print the first 10 natural numbers.

Pre-Knowledge (Before you start!)

• Basic Kotlin Syntax.
• Kotlin Functions.
• Loops in Kotlin.
• Range Operator.
• Printing Output.

Hints (Try before looking at the solution!)

• Define the main() Function.
• Use a For Loop.
• Print Each Number.
• Test the Program.
• Common Errors to Avoid:
  • Forgetting the range operator.
  • Misplacing loop boundaries.
  • Using print() instead of println().

Sample Solution:

Kotlin Code:

fun main() {
    for (i in 1..10) {
        println(i)
    }
}

Sample Output:

1
2
3
4
5
6
7
8
9
10

Explanation:

In the above exercise,

• The main() function serves as the program's entry point.
• The for loop iterates from 1 to 10 (inclusive) using the range operator ‘..’.
• Inside the loop, the current number i is printed using the println() function.
• The loop continues until all numbers from 1 to 10 have been printed.
