of FlyHigh Airlines and is in the process of testing the software. While testing the software, the
team encounters the following issues:
The operations-related data of FlyHigh Airlines is stored in a central database. The software
fails to respond to user inputs, if there is a connectivity problem with the database. Add the code
snippet that the development team should use to ensure that the application shows a userfriendly
message, if such a situation arises in future.[5 Marks]
The application used to calculate the cost of carrying additional luggage results in erroneous
amount, if the weight of the luggage is a fractional number. Help the development team modify
the code snippet so that the cost of carrying additional luggage is calculated correctly. [5 Marks]

Dwayne runs a money lending business in which he offers different types of loans, such as
personal loan, car loan, and home loan, on high rate of interest to those individuals who cannot
get a loan from the commercial banks. As part of his business activities, Dwayne maintains a
customer details register that contains the following information:
The contact details of all those persons to whom Dwayne has lent money.
The amount of money lent to each person.
The interest rate charged from each person.
Over the years, Dwayne's business has grown tremendously. This has caused an exponential
increase in the number of customer details that he needs to maintain. As Dwayne uses a physical
register to maintain the customer details, he faces the following problems:
In case the contact details of a customer changes, Dwayne needs to delete the previous entry
and add a new entry for the respective customer.
The numbers of errors committed during the data entry process are high.
To address the preceding issues, Dwayne decides to computerize the task of maintaining the
customer details. Therefore, he hires Elina, a freelance software developer, for the task. Elina
conducts a meeting with Dwayne and notes the following requirements:
Dwayne does not have the budget to implement RDBMS. However, he wants that data is
available all the time. As a result, the application must store the customer details persistently on
Dwayne's computer.
The application should allow Dwayne to create and modify the customer details as per his
requirements.
The application needs to store the customer details in such a way that the details can be read by
only the application. Therefore, if the customer details file is opened by anyone other than the
application, the content should not be readable as plain text.
Question:
Elina decides to develop the application using C#. Analyze the preceding scenario and answer the
following questions:
Which classes of the .NET Framework should Elina use to implement file input and output
operations in the application? Justify the reason for the same. [5 Marks]
Describe the different methods of the classes that Elina would be using to implement file input
and output operations in the application.

The technical team of AutoZig Enterprise wants to develop a feature for the supervisors. Using
this feature, the details of the automobile part can be added but it should not be visible to other
employees of the company. This feature is useful for the automobile parts that are new and are
in the field for a trial run. As a software developer of WebSoft Solutions Pvt. Ltd., develop code
so that the information of a specific automobile part can be hidden from other employees of the
company. If an unauthorized user tries to access the information about a specific part, it should
display the error message, "Unauthorized Access". Develop the code that meets the
requirements given in the problem statement. Use the concept of access specifiers while
developing the code.

The application should be able to count the number of automobile parts sold every week
depending upon the number of new entries of parts in the application. If a part is not sold for
more than six months after its date of manufacture, the application should prompt a message,
"Urgent Sale Required". Help the programmers at WebSoft Solutions Pvt. Ltd. to develop the
code for this feature
