Quiz Grader

For this assignment, you will write a program that grades an online quiz. The program asks the

student to enter his/her answer to 10 multiple-choice questions. The program stores the

student’s responses in an array and then compares those responses to the correct answers to

determine the student’s grade.

The correct answers are:

Your program must use this main procedure. You must implement the inputAnswers and

numCorrect procedures and test the program to make sure it works correctly.

For this program both correctAnswers and

given are arrays of characters.

Note that given is an out parameter to

inputAnswers, and numRight is an out

parameter to numCorrect.

Raptor makes this a little tricky because even if

a user enters a single character as input, Raptor

considers it a string instead of a character. To

convert an input string to a character, I

recommend this procedure.

Hints

You will need to create two procedures for this assignment. You do that in the same way you

did for Lab #6. If you have forgotten, review the video in lesson #6.

Lesson #7 has an example of inputting values into an array, and looping through those values.

You will perform similar actions for this assignment.

Extra Credit (10 Points)

For extra credit, modify your program so that it adds an extra line after the quiz grade that

displays which question numbers the student got wrong. It could look like this:

You answered the following questions incorrectly: 2 6

You may either include the extra credit in your initial submission, or in an additional

submission.
