I am working on a C++ Programming question using array can someone help me figure out how to write this program:

The local Driver's License Office has asked you to write a program that grades the written portion of the driver's license exam. The test has 20 multiple choice questions.Here are the correct answers 1.B 2.D 3.A 4.A 5.C 6.A 7.B 8.A 9.C. 10.D 11.B 12.C 13.D 14.A 15.D 16.C 17.C 18.B 19.D 20.A ...Your program should store the correct answers shown above in 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 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 question 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 D as answer
