Dwayne runs a money lending business in which he offers different types of loans, such as personal loan, car 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:
1:The contact details of all those persons to whom Dwayne has lent money.
2:The amount of money lent to each person.
3: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 physicalregister to maintain the customer details, he faces the following problems:
1: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.
2: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:
1: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.
2:The application should allow Dwayne to create and modify the customer details as per his requirements.
3: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:
1: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.
2:Describe the different methods of the classes that Elina would be using to implement file input and output operations in the application.

Elina develops the customer details maintenance application and the EMI calculator application and provides both the applications to Dwayne for testing. While testing the applications, Dwayne discovers the following problems:
1.The application displayed a message to the user to enter the path of the customer details file. However, the customer details maintenance application crashed as Dwayne mistakenly entered the wrong file path. Therefore, he asks Elina to modify the application so that it does not crash due to similar errors. Modify the code that Elina needs to accomplish the preceding task.
2.The EMI calculator application crashed when Dwayne accidentally entered zero as the rate of interest. Therefore, he asks Elina to modify the application so that it displays an error message if the principal amount, rate of interest, or tenure of the loan entered is invalid. Add the code snippet that Elina should use to modify the application according to the preceding requirements.
