Define a class Car having variable speed of car, number of wheels and type = SUMO or TOYOTA and some methods. Define a class Bike having variable speed of bike, number of vehicles and type=SPORT or RACING Extend class Car and to derive another class AutomaticCar that has a method gear_change. gear should change automatic depending upon speed. Give your own logic for changing the gear. For class Bike write constructors that take no argument and take one arguments. Create an object of class AutomaticCar and call method gear_change. Create an object of class Bike and write method setSpeed, getSpeed,setColour.
