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.

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.

The c# console-based application developed must be submitted in a zip folder on the LMS
in the available link. The zip folder should include:

QUESTION 2:

S.B.Consult Ltd, recognized as the leader in hospital supplies, has received an invitation to supply FBC, ECG, and dental machines to Justab Hospital in Kasoa. The contract will be for 10 years, and management is considering appraising the investment to enable them present their proposals for the contract. The following information was extracted from the recently published accounts of S.B. Consult Ltd.

The Treasury unit of S.B.Consult Ltd has estimated that it will require GH¢ 10 million to finance the new project. The total amount would be raised through 10% Irredeemable bonds at the current market price. The cost of Preference shares and Bonds will not change but equity shareholders will demand an increase of 20% on the current cost of equity.

S.B.Consult Ltd has a beta of 0.8, the market risk premium for the steel industry is 6.25%, and the Government of Ghana Bond rate is 20%. The current market price for Irredeemable Bonds of GH¢1,000 nominal value is GH¢850.

S.B. Consult Ltd’s dividend policy is to pay constant dividend and this policy will not change into the foreseeable future. The recent dividend paid was GH¢20 per share. S.B. Consult Ltd is a Free Zones Company and therefore pays tax at a rate of 8%.

Required:

i) Calculate the current market capitalization of S.B. Consult Ltd.                    

(Hint: ?=??+ ? (??−??))

An insurance company believes that people can be divided into two classes: those who are an accident prone and those who are not. The company’s statistics show that an accident-prone person will have an accident at some time within a fixed 1-year period with probability .4, whereas this probability decreases to .2 for a person who is not accident-prone.
(i) If we assume that 30 percent of the population is accident prone, what is the probability that a new policyholder will have an accident within a year of purchasing a policy?
(ii) Suppose that a new policyholder has an accident within a year of purchasing a policy. What is the probability that he or she is accident-prone?

Two boxes containing marbles are placed on a table. The boxes are labeled B1 and B2. Box B1 contains 7 green marbles and 4 white marbles. Box B2 contains 3 green marbles and 10 yellow marbles. The boxes are arranged so that the probability of selecting box B1 is 1/3 and the probability of selecting box B2 is 2/3 FATIMAH is blindfolded and asked to select 3 marbles. She will win a color TV if she selects a green marble.
(i) What is the probability that FATIMAH will win the TV (that is, she will select a green marble)?
(ii) If FATIMAH wins the color TV, what is the probability that the green marble was selected from the first box?

One-half percent of the population has CORONA Virus. There is a test to detect CORONA. A positive test result is supposed to mean that you have CORONA but the test is not perfect. For people with CORONA, the test misses the diagnosis 2% of the times. And for the people without CORONA, the test incorrectly tells 3% of them that they have CORONA.
(i) What is the probability that a person picked at random will test positive?
(ii) What is the probability that you have CORONA given that your test comes back positive?

A device is composed of two components, A and B, subject to random failures. The components are connected in parallel and, consequently, the device is down only if both components are down. The two components are not independent. We estimate that the probability of:
a failure of component A is equal to 0.2;
a failure of component B is equal to 0.8 if component A is down;
a failure of component B is equal to 0.4 if component A is active.
(a)

Calculate the probability of a failure
(i) of component A if component B is down
(ii) of exactly one component
(b)

In order to increase the reliability of the device, a third component, C, is added in such a way that components A, B, and C are connected in parallel. The probability that component C breaks down is equal to 0.2, independently of the state (up or down) of components A and B. Given that the device is active, what is the
probability that component C is down?
