Question 6:

Develop the following class Hierarchy:
1-Vehicle Class with the following members:
a-engine of type double(Engine Size)
b-price of type double (Price of the vehicle)
c-constructor to set the variables
d-getEngine() to return the engine size
e-toString() to return the information about the vehicle
2-Car class is -a vehicle with the following members;
a-model of type string(model of the car)
b-constructor to set the variables
c-calcTax() to return the tax on the car which is calculated according to the following  if the engine size is less than 1.6 the tax will be 40% of the price otherwise the tax will be 50% of the price
d=toString() to retuurn the information about Car in addition to tax and final price
3-Create two Car objects:
a-the first is 2.0,10000,Mazda
b-the second is created by getting its values from use

Explanation / Answer
