The local Driver’s License Office has asked you to write a program that grades the written portion of the driver’s exam. The exam has 20 multiple choice questions. A data file contains the correct answers as follows:
B D A A C A B A C D B C D A D C C B D A
Your program should read above correct answers from the file to 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 of showing the question numbers of the incorrectly answered questions.
Input Validation: only accept the letters of A, B, C or D as answers.
• Answers of 20 questions
• A message to indicate if the student has passed the exam.
