Rewrite so that instead of checking an individual file the user specifies the program checks an entire directory. As the program tests each file, it should both print the results to the screen and simultaneously to a file called Filetypes_in_. The program should use a loop so that after each run, the user is prompted again for a directory name to process, or can enter Q or q to quit. Constraints: The program must successfully detect whether the value entered is a directory -- and process it -- or another type of file. If the value entered is not a directory the user should be informed.
