Kotlin program for Nested class and Inner class

class Car {
    var make: String
    var model: String
    var year: Int
 
    inner class Engine {
        var horsepower: Int = 0
        var cylinders: Int = 0
 
        fun getEngineInfo(): String {
            return "$horsepower horsepower, $cylinders cylinders, in a $make $model"
        }
    }
 
    fun getInfo(): String {
        return "$make $model, year $year"
    }
}
 
fun main() {
    val myCar = Car()
    myCar.make = "Toyota"
    myCar.model = "Camry"
    myCar.year = 2020
 
    val engine = myCar.Engine()
    engine.horsepower = 250
    engine.cylinders = 6
 
    println(engine.getEngineInfo())
}

Output:

250 horsepower, 6 cylinders, in a Toyota Camry
