If the directory name exists, display a list of the files in it; otherwise, display the following message, Directory foo does not exist, to indicate the directory does not exist (foo would be the name of the directory to be checked) . Create as many test directories and files as necessary to test your program. An example of the program is shown below: Enter a directory >> lorem lorem contains the following files lorem/ipsum.txt Enter another directory or type end to quit >> foo Directory foo does not exist
