Original question:

Write a quiz program on a topic, about which you are knowledgeable. This quiz can be work related, general knowledge or any set of questions where there is a specific answer. Ignore questions where long descriptions or general answers needed. The program should display the questions, one at a time, and possible answers, and accept an answer from the user. If the answer is correct, the program should go on to the next question. If it is incorrect, store the question for the second attempt and go on to the next question. When the list of questions has ended, the questions that were missed previously, or answered incorrectly, should be displayed again, in their original order. Keep a count of the correct answers for each category of questions and display the final count after two attempts. Also, display the correct answer, when necessary, in the second round of questioning.

Limit the quiz to ten (10) questions. Include questions from both true/false and multiple-choice categories. Four (4) possible answers should be listed in multiple-choice questions.

This is what I did last week.

This week, you will optimize the existing project code by implementing methods. Additionally, you will test the code for non-permissible input value(s) of the variable(s) and document your test results. Improve your code by adding a statement that displays an error message.

This is what I need to do this week ( what I need Help for)

This week, you will create an object-oriented model for your project. You will learn to identify and describe the classes, their attributes and operations, as well as the relations between the classes. Create a class diagram using free online UML software of your choice (for example, Creately (Links to an external site.)Links to an external site.). Document the results of your work.

I dont know how to accomplish the taskgiven above.Please help. Thanks!
