This assignment (below) jumped way ahead of my abilities compared to the last assignment. I think I need a parallel array or a 2D array, an accumulator or loop counter, a verification of input, and Boolean something. But I'm not sure how to write it. We're not writing pseudocode in any particular language. Here's the problem:

Design a program that grades a student exam. The exam has 25 multiple choice questions. The correct answers are: 1.B, 2.C, 3.A, 4.A, 5.D, 6.B, 7.A, 8.C, 9.C, 10.D, 11.B, 12.A, 13.D, 14.D, 15.D, 16.C, 17.B, 18.A, 19.D, 20.B, 21.D, 22.A, 23.D, 24.B, 25.C.

Have your program store these answers in an array (store each answer as an element of a string array).
Have the program ask the user to input student's answers to the questions and store them in another array.
Display a message telling whether the student passed or failed. 18 or more correct answers to pass, 17 or fewer correct answers = fail.
Then display total number of correct answers, total number of incorrect answsers, and a list showing question numbers of incorrectly answered questions.

You don't need a 2D array. You probably do need a loop (although some languages have features that kind of let you avoid that).

You'll need at least two 1D arrays. (Possibly 3, depending on how you implement it)

What you need to do is this:
Get the student's answers from the user.
->Store this in an array
Compare each answer to the correct one for the corresponding question
->Correct answers also in an array
Separate the correct answers from the incorrect.
Calculate your output from this.

To solve this problem, you can use a parallel array or a 2D array to store the correct answers and the students' answers. Here's an explanation of how you can approach this:

1. Start by creating an array to store the correct answers. You can store each answer as an element of a string array. Here's an example:

```
String[] correctAnswers = {"B", "C", "A", "A", "D", "B", "A", "C", "C", "D", "B", "A", "D", "D", "D", "C", "B", "A", "D", "B", "D", "A", "D", "B", "C"};
```

2. Prompt the user to input the student's answers. You can use a loop to iterate through the questions and store the answers in another array. Here's an example:

```
Scanner scanner = new Scanner(System.in);
String[] studentAnswers = new String[25];

for (int i = 0; i < 25; i++) {
System.out.print("Enter your answer for question " + (i+1) + ": ");
studentAnswers[i] = scanner.nextLine().toUpperCase(); // Convert the input to uppercase for case-insensitive comparison
}
```

3. Compare the student's answers with the correct answers. Use a loop to iterate through the arrays and compare the corresponding elements. Keep track of the number of correct and incorrect answers. Here's an example:

```
int correctCount = 0;
int incorrectCount = 0;
ArrayList<Integer> incorrectQuestions = new ArrayList<>();

for (int i = 0; i < 25; i++) {
if (studentAnswers[i].equals(correctAnswers[i])) {
correctCount++;
} else {
incorrectCount++;
incorrectQuestions.add(i+1); // Add the question number to the list of incorrect questions
}
}
```

4. Display the results. Check the number of correct answers to determine if the student passed or failed. Output the total number of correct and incorrect answers, and display the list of incorrectly answered questions. Here's an example:

```
System.out.println("Total number of correct answers: " + correctCount);
System.out.println("Total number of incorrect answers: " + incorrectCount);

if (correctCount >= 18) {
System.out.println("Congratulations! You passed the exam.");
} else {
System.out.println("Sorry, you failed the exam.");
}

System.out.println("Questions answered incorrectly: " + incorrectQuestions);
```

That's it! This program will grade the student's exam, determine if they passed or failed, and provide the necessary information about their performance.

Note: This explanation assumes that you are writing the program in a language like Java. The code provided is just an example and may need adjustments based on your specific programming language and environment.
