call to the constructor

Thanks for pointing this out! After some thought, I'd like to make a slightly bigger change than you are suggesting. Please take a look at my comment.

After thinking about it, I'd like to remove this code snippet and bring the example sooner to make it clearer that the constructor is called. Can you apply my below suggestions?

Suggested change

	```kotlin
	If you can't use interfaces or abstract classes, you can explicitly make a class inheritable by declaring it as **open**.
	To do this, use the `open` keyword before your class declaration:
	```kotlin
	open class Vehicle(val make: String, val model: String)
	```
	To create a class that inherits from another, add a colon after your class header followed by a call to the constructor
	of the parent class that you want to inherit from. In this example, the `Car` class inherits from the `Vehicle` class:
	```kotlin
	open class Vehicle(val make: String, val model: String)
	class Car(make: String, model: String, val numberOfDoors: Int) : Vehicle(make, model)
	fun main() {
	// Creates an instance of the Car class
	val car = Car("Toyota", "Corolla", 4)
	// Prints the details of the car
	println("Car Info: Make - ${car.make}, Model - ${car.model}, Number of doors - ${car.numberOfDoors}")
	// Car Info: Make - Toyota, Model - Corolla, Number of doors - 4
	}
	```
