Kotlin Function: Print message without return

Kotlin Function: Exercise-6 with Solution

Write a Kotlin function that prints a message and does not return anything.

Sample Solution:

Kotlin Code:

fun printMessage(message: String) {
    println(message)
}
fun main() {
    printMessage("Hello, world!")
}

Sample Output:

Hello, world!

Explanation:

The "printMessage()" function takes a parameter message of type String. Inside the function, it prints the message using the println function.

In the main function, we call the "printMessage()" function and provide the message "Hello, world!" as an argument. The function prints the message to the console.

Since the "printMessage()" function does not return any value (unit-returning function), its return type is Unit, which is the default return type for functions that do not specify a return type explicitly.
