Kotlin Function: Print person details with named arguments

Last update on August 27 2025 12:41:26 (UTC/GMT +8 hours)

Write a Kotlin function that takes named arguments `name`, `age`, and `city` and prints the details of a person.

Pre-Knowledge (Before you start!)

Basic Kotlin Syntax.
Kotlin Functions.
Named Arguments.
Printing Output.

Hints (Try before looking at the solution!)

Define the Function.
Print the Details.
Use Named Arguments.
Test with Different Values.
Common Errors to Avoid:
- Forgetting named arguments.
- Misplacing println() statements.
- Not validating inputs.

Sample Solution:

Kotlin Code:

fun printDetails(name: String, age: Int, city: String) {
    println("Name: $name")
    println("Age: $age")
    println("City: $city")
}

fun main() {
    printDetails(name = "Gerhard Rikuto", age = 22, city = "New York")
}

Sample Output:

Name: Gerhard Rikuto
Age: 22
City: New York

Explanation:

In the above exercise -

The printDetails() function takes three named arguments: name of type String, age of type Int, and city of type String.
Inside the function, it prints the details of a person by accessing the values of the named arguments. The details are printed using println().
In the main function, we call the "printDetails()" function and provide the values for the named arguments explicitly.

Go to:

PREV : Calculate circle area with default pi.
NEXT : Print a greeting message with person's name.
