Your program should store the correct answers shown above in an array. It should ask the user to
enter the student's answers for each of the 20 questions, and the answers should be stored in another
array. After the student's answers have been entered, the program should display a message
indicating whether the student passed or failed the exam. (A student must correctly answer 15 of
the 20 questions to pass the exam.) It should then display the total number of correctly answered
questions, the total number of incorrectly answered questions, and a list showing the question
numbers of the incorrectly answered questions.
Input Validation: Only accept the letters A, B, C, or…
7. Given the following code, what initial values for num will cause an error during execution?

else if (num 0
B. num > -100 and num < 0
C. num < 0
D. None of these will cause an error.
