Create a program named TestFileAndDirectory that allows a user to continually enter directory names until the user types end. If the directory name exists, display a list of the files in it; otherwise, display a message indicating the directory does not exist. If the directory exists and files are listed, prompt the user to enter one of the filenames. If the file exists, display its creation date and time; otherwise, display a message indicating the file does not exist. Create as many test directories and files as necessary to test your program.
