Kotlin Function: Print person details with named arguments

Last update on February 04 2025 08:17:22 (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.
