Driver’s License Exam
The local driver’s license office has asked you to write a program that grades the written position of the drivers license exam. The exam has 20 multiple choice questions. Here are the correct answers:
l. B | 6. A | 11. B | 16. C |
2. D | 7. B | 12. C | 17. C |
3. A | 8. A | 13. D | 18. B |
4. A | 9. C | 14. A | 19. D |
5. C | 10. D | 15. D | 20. A |
A student must correctly answer 15 of the 20 questions to pass the exam.
Write a class named DriverExam that holds the correct answers to the exam in an array field. The class should also have an array field that holds the student’s answers. The class should have the following methods:
• passed. Returns true if the student passed the exam, or false if the student failed
• totalCorrect. Returns the total number of correctly answered questions
• totalIncorrect. Returns the total number of incorrectly answered questions
• questionsMissed: An int array containing the question numbers of the questions that the student missed
Demonstrate the class in a complete program that asks the user to enter a student’s answers and then displays the results returned from the DriverExam class’s methods.
Input Validation: Only accept the letters A, B, C, or D as answers.
