3. (10 pts) Tommy has an extensive collection of digital photos taken during adventures in nature and biking trips over the years. They are currently stored on his computer's hard drive. He d like to
make back-up copies of them on USB flash drives. Suppose one flash drive has a 32 GB capacity and each image file has a size of 12.5 MB.

If each flash drive can store/transfer photos at a rate of 60 MBps (Megabytes per second), how long would it take to transfer the entire collection from the hard drive to the flash drive?

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
