Question

Consider the code and output below. Is Car more likely to be a struct or a class?

func test(prototype: Car) -> String {
prototype.speed = 100 // Assume that speed is an Int variable
prototype.saveDiagnostics() // Assume saveDiagnostics stores information about changes to the car state
prototype.speed = 120
prototype.saveDiagnostics()
prototype.speed = 200
prototype.saveDiagnostics()
return prototype.GetDiagnostics() // Assume GetDiagnostics returns a diagnostics report
}

var myCar = Car(speed: 0)
print("Speed before testing: \(myCar.speed)")
var result = test(prototype: myCar)
print("Speed after testing: \(myCar.speed)")

Screen output:

Speed before testing: 0
Speed after testing: 0

1. Car is a class

2. Car is a struct

3. Car is neither a class nor a struct
