Create a class motorcycle that contains the following attributes: The name of motorcycle, the direction of motorcycle (E, W, N, S) and the position of motorcycle (from imaginary zero point) The class has following member functions: A constructor to initialize the attributes, Turn function to change direction of the motorcycle to one step right side. Overload the turn function to change the direction to any side directly. It should accept the direction as parameter. More function to change the position of motorcycle away from zero point. It should accept the distance as parameter
