PROG 24310: Inheritance, Polymorphism, Copy Constructors, Operator Overloading, Generic Programming - IT Assignment Help

Assignment Task:

Objectives: Inheritance, polymorphism, copy constructors, operator overloading, generic programming 

Question 1 Write a C++ program that maintains information regarding cars sold by a dealership. Assume that the dealership deals in old and new cars. Each car has a Vehicle Identification Number (VIN), a Make, a Model Year, List Price and Discount. The default value for discount is zero. For used cars, an additional information regarding the distance run by the car is also maintained. 

The sale price of cars is calculated as per following logic: 

• For new cars: Sale Price = List Price – Discount 

• For old cars: Sale Price = List Price – Discount - Depreciation. Assume that a used car depreciates by .3% for each 10,000 kM it has travelled. 

The program should: 

i. Define a class CarInventory to maintain car instances. Make sure the inventory does not allow multiple cars with the same VIN. [5 Marks]

ii. Define the classes to represent old and new cars, with required attributes, getters & setters, constructors. [10 Marks]

iii. Define functions to compute sale prices of new and old cars. [5 Marks]

iv. Add 4 cars (2 old and 2 new) to the CarInventory and use polymorphism to print the sale price of each car and the total sale price of all the cars. [5 Marks] 

Question 2 Refer to the class Fraction (Lecture-4b Introduction to Object Oriented Programming). Add the following operations to the class: 

1. Addition of two fractions using the + operator E.g. given Fraction f(3, 4), g(4, 3); f+g should give a fraction with numerator 25 and denominator 12

2. Addition of a fraction and an integer number using the + operator E.g. given Fraction f(3, 4); f+3 should give a fraction with numerator 15 and denominator 4.
