2,380 PointsWhere to set default for wheels, doors?
Not quite sure about where to set the default for the wheels, doors. Help!
class Vehicle {
let wheels: Int
let doors: Int
// Designated initializer
init(wheels:Int, doors:Int){
self.wheels = wheels
self.doors = doors
}
}
class Car: Vehicle {
// A car must default to 4 wheels and 4 doors
var auto = Car(wheels = 4, doors = 4)
init(){
// call super.init
super.init()
}
}

14,575 PointsHey Paul, you are creating an instance of car inside the class. First delete the βvar autoβ instance, and then on the super.init() add the default values. It should look something like this.
super.init(wheels: 4, doors: 4)
remember, with the super.init you are calling the initializer from the super class βVehicleβ. All you are doing now is adding default values to it. Please let me know if it helps.

2,380 PointsThank you for the input; that worked.
I need to practice this more in order to get better, but I think that I get the general idea.
Thanks again!
