[Solved] Consider the function:fun reserveSeat(name: String, eventDate: String, seatType: String = "Regular") { println("Reservation for $name on $eventDate, Seat:... | Kotlin

Kotlin - Functions

Consider the function:

fun reserveSeat(name: String, eventDate: String, seatType: String = "Regular") {
    println("Reservation for $name on $eventDate, Seat: $seatType")
}

Which call correctly uses named arguments to reserve a seat for "Emma" on "2024-12-15" with the default seat type?

AreserveSeat(name = "Emma", eventDate = "2024-12-15")

BreserveSeat("Emma", seatType = "Regular", "2024-12-15")

CreserveSeat(eventDate = "2024-12-15", "Emma")

DreserveSeat(seatType = "Regular", name = "Emma", eventDate = "2024-12-15")

Step-by-Step Solution

Solution:

Step 1: Understand default parameters
The parameter seatType has a default value, so it can be omitted.
Step 2: Check named argument usage
reserveSeat(name = "Emma", eventDate = "2024-12-15") correctly names the first two parameters and omits the default one.
Step 3: Identify invalid calls
Options B and C mix positional and named arguments incorrectly; D names all but unnecessarily names the default parameter.
Final Answer:
reserveSeat(name = "Emma", eventDate = "2024-12-15") -> Option A
Quick Check:
Omit default parameters or name them explicitly. [OK]
