In this exercise you will be doing some more work on remote control cars.
An experimental car has been developed and the test track needs to be adapted to handle both production and experimental models. The two types of car have already been built and you need to find a way to deal with them both on the test track.
In addition, production cars are beginning to have some success. The team boss is keen to maintain the competitive spirit by publishing a ranking of the production cars.
Please add a method to the
IRemoteControlCar interface to expose the implementations of
Drive() for the two types of car.
TestTrack.Race(new ProductionRemoteControlCar()); TestTrack.Race(new ExperimentalRemoteControlCar()); // this should execute without an exception being thrown
Please add a property to the
IRemoteControlCar interface to expose the implementations of the
DistanceTravelled property for the two types of car.
var prod = new ProductionRemoteControlCar(); TestTrack.Race(prod); var exp = new ExperimentalRemoteControlCar(); TestTrack.Race(exp); prod.DistanceTravelled // => 10 exp.DistanceTravelled // => 20
Please implement the
IComparable<T> interface in the
ProductionRemoteControlCar class. The default sort order for cars should be ascending order of victories.
Implement the static
TestTrack.GetRankedCars() to return the cars passed is sorted in ascending order of number of victories.
var prc1 = new ProductionRemoteControlCar(); var prc2 = new ProductionRemoteControlCar(); prc1.NumberOfVictories = 3; prc2.NumberOfVictories = 2; var rankings = TestTrack.GetRankedCars(prc1, prc2); // => rankings == prc1
