(i) Explain the relationship between Line 1 , Line 2 and Line 3.
Ans Line 1 is a parameterized constructor of derived class RacingCar that accepts values for
its instance variables turnRadius ,speed . It accepts clr,seats,l,w to initialize the
instance variables colour with clr , seatingCapacity with seats of base class Car
through its constructor function/__init__()(Line 2) and invokes constructor
function/__init__() of base class Vehicle to initialize its instance variables length with l
and width with w(Line 3).

(2 marks for appropriate answer justifying the passing of parameters to initialize
members of base class via __init__( ))

(ii) Predict the output that will be produced on the execution of the following statements :

Ans
