Driver’s License Exam

The State Department of Motor Vehicles (DMV) has asked you to write a program that grades the written portion of the driver’ s license exam, which has 20 multiplechoice questions . Here are the correct answers:

1. B 5. C 9. C 13. D 17. C
2. D 6. A 10. D 14. A 18. B
3. A 7. B 11. B 15. D 19. D
4. A 8. A 12. C 16. C 20. A

To do this, you should create a TestGrader class. The class will have an answers array of 20 characters, which holds the correct test answers. It will have two public member functions that enable user programs to interact with the class: setKey and grade. The setKey function receives a 20-character string holding the correct answers and copies this information into its answers array. The grade function receives a 20-characte r array holding the test taker’s answers and compares each of their answers to the correct one. An applicant must correctly answer 15 or more of the 20 questions to pass the exam. After “grading” the exam, the grade function should create and return to the user a string that includes the following information:

• A message indicating whether the applicant passed or failed the exam

• The number of right answers and the number of wrong answers

• A list of the question numbers for all incorrectly answered questions

The client program that creates and uses a TestGrader object should first make a single call to setKey, passing it a string containing the 20 correct answers. Once this is done, it should allow a test taker's 20 answers to be entered, making sure only answers of A-D are accepted, and store them in a 20-character array. Then it should call the grade function to grade the exam and should display the string the function returns. The program should loop to allow additional tests to be entered and graded until the user indicates a desire to quit.

An online book club awards points to its customers based on the number of bookspurchased each month . Points are awarded as follows:Books Purchased01234 or morePoints Earned051530soWrite a program that asks the user to enter the number of books purchased this monthand then displays the number of points awarded .
C language The program should allow users to add, subtract, multiply, and divide fractions. The program should display a menu and prompt the user for a mathematical operation, until they enter 5 to exit. The menu should give the user the option to add, subtract, multiply or divide fractions, or exit. After the user chooses their option, they should be prompted to input two fractions. The result of the arithmetic should then be displayed to the screen.   Requirements main()Functionality: This main function should prompt the user for a menu option until they enter 5. If the user doesn't choose Option 5 to end the program, it should get two fractions from the user. It should decide, based on the menu option which actions to perform on the fractions. Option 1 adds the two fractions together. Option 2 subtracts the first fraction from the second. Option 3 multiplies the two fractions together. Option 4 divides the first fraction by the second one. In addition to the main functions, your…
ITP 100 Programming Logic & Design Project In this project, you will design a program to perform the following task:  Design a program, the STAR Movie Rating App, which can be installed in a kiosk in theaters and patrons can immediately give their rating of a movie they’ve just seen. Each theater patron enters a value of 0, 1, 2, 3, or 4 indicating the number of stars that the patron awards to the App’s featured movie of the week.  If a user enters a star value that does not fall in the correct range, the program will prompt the user continuously until a correct value is entered. The program executes continuously until a negative number is entered to quit. At the end of the program display: the number of ratings given the average star rating for the movie of the week the following message depending on the average rating. 3 or better – “Great movie choice!” 2 up to 3 – “Good movie choice!” 1 up to 2 – “Not a Good movie choice.” 0 up to 1 – “Bowling would have been a better…
