Quiz Grader

COSC 1436 Lab #8 Flowchart

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: 

 

1 2 3 4 5 6 7 8 9 10

B C A D B A D C A B

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.  

Sample Output (input in BOLD)

Please enter your answer for question #1  B

Please enter your answer for question #2  B

Please enter your answer for question #3  A

Please enter your answer for question #4  D

Please enter your answer for question #5  B

Please enter your answer for question #6  C

Please enter your answer for question #7  D

Please enter your answer for question #8  C

Please enter your answer for question #9  A

Please enter your answer for question #10 B

 

Your quiz grade is 80%

 

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.

 

Lab 08 C++

 

 

Using the flowchart for Lab #08 as a guide, write a C++ program that does the same

thing. Your C++ program must also use two procedures (called functions in C++) to input

the student responses and to determine how many answers were correct.

 

Remember Raptor arrays start at 1, but C++ arrays start at 0.

 

Here is what the function header for inputAnswers should look like;

 

 void inputAnswers(char given[ ] )

 

The numRight function should return an int.

 

There is no extra credit for the C++ version of this assignment, but you may, if you wish,

submit a program which is the C++ equivalent of the extra credit version of the Lab 08

Flowchart.

 

Test your program to make sure it works properly, and then upload just the C++ code in

the TurnItIn assignment.
