Assignment
Weightage: 25%
Submission deadline: Session 12
The purpose of assessment is to assess students on the following Learning Outcomes:
LO1: Use problem solving techniques and program design methods to translate a problem
description to a formal program specification with core programming concepts, such as
computer storage and data types, decision structures, loops and object-oriented programming
concepts, and error handling
LO2: Differentiate various object-oriented programming constructs, including classes,
inheritance, polymorphism, and encapsulation.

Objective(s)
This is an individual assessment. In this assignment, you are required to develop a Visual
C# program using Visual Studio. The aim of the assignment is to prepare students to adapt their
knowledge and understanding gained in the unit into changing demands relevant to the software
development.
Assignment Description
Write a C# code that creates objects and classes with their member functions for KrisFlyer,
a Singapore Airlines Loyalty program. You are asked to write an inheritance hierarchy discount
system that benefits KrisFlyer members program to calculate their profit.
A brief about KrisFlyer is that it is useful for those who fly on Singapore Airlines (its
partners like Virgin Australia and Air New Zealand) frequently. KrisFlyer miles can be earned
through credit cards, flying and bonus miles promotions. The miles can be redeemed for award
flights in all categories. It has three types of memberships namely Basic, Elite Silver and Elite
Gold. When registered for the first time, all the customers get instant access to the basic

membership level of KrisFlyer. In 2020, Singapore Airlines offers a flat 10%, 20% and 30%
discount to its Basic, Elite Silver and Elite Gold members respectively for all services provided.
Customers without membership receive no discount. The students have to implement basic OOPs
concepts such as inheritance, polymorphism and encapsulation.
Inheritance
Base class: Create an inheritance hierarchy to represent various types of memberships. Use
KrisFlyer as the base class of the hierarchy, then include derived classes Basic, Elite Silver and
Elite Gold that deriver from KrisFlyer. Base class KrisFlyer should have data members
representing name, membership, flight, price for flight, number of passengers for the members.
The constructor should initialize these data members. Ensure that flight price and number of
passengers contain positive values. KrisFlyer should include a public member function
calculateCost() that returns a double indicating the cost by multiplying the price for flight by the
number of passengers.
Derived class: Basic, Elite Silver and Elite Gold should inherit the functionality of base
class KrisFlyer, but also include a data member that represents a discount that the reward program
has offered recently. All the derived class’s constructor should receive a value to initialize this data
member. In 2020, Singapore Airlines offers a flat 10%, 20% and 30% discount to its Basic, Elite
Silver and Elite Gold members respectively for all services provided. All the derived members
should redefine calculateCost() so that it applies the discount to the booked flights. It shall compute
the total bill if a customer purchases y tickets for a price of $x for each flight for their visit using
Krisflyer.
Your system shall consist of four classes: 1. KrisFlyer (base class), derived classes
including Basic, Elite Silver, Elite Gold.
Polymorphism
Implement a method display() that displays all the records of the system. Another form of
the method display(string cust_name) that displays records related to the customer name passed in
the argument.

Encapsulation
Define the instance variables private/ public so that they cannot/can be accessed from
outside the class. Implement getter and setter method for the variables in the program.
Write a program that implements basic Object-oriented concepts including encapsulation
polymorphism and inheritance. Also, the program is expected to get the basic input from the user
based on either console/Desktop.
The student is expected to do the following tasks:
1. Draw the class diagram of the given scenario
2. Write the c# classes with suggested data members and functions
3. Write the base and derived classes for implementing inheritance in the program.
4. Implement polymorphism and encapsulation to check for accessibility of data members
and different form of the data member
5. Write the main logic that takes input from the user members with their bookings
6. Write the code to display the output as displayed (it is a sample)
Expected output

The given output is a sample. The student is free to use creative ideas to display the output of the
program. It needs to be an interactive session where the user feeds in dynamic information.

Code related Guidelines
1. Your c# console-based application should include the following:
a. The code should have a consistent, professional and well-organized appearance.
b. Carefully chosen, meaningful identifier names
c. Code is well organized: clear, simple, & DRY (Don't repeat Yourself)
d. Thoughtful comments, where needed, expressed in concise, precise English.
e. Code should compile without errors
2. The developed system takes input and handles the error in friendly manner.
3. Your project must adhere to OOPS concepts with implementation guidelines including
modularity, reusability, extensibility, maintainability and adaptability.
