An application used by the human resources (HR) department needs to be improved. You need to use various string manipulation properties and methods to ensure all data entered by a user are accurate and stored correctly. The users of the HR application have entered some employee social security numbers (SSNs) with dashes (such as 222-33-4444) and some without dashes (such as 222334444). You need to remove all dashes from any SSN that contains dashes. You will use the method to edit the code so that only numeric characters are stored.

To check whether your writing is clear , you can

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.
