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.
