When I run the program from the command line it looks as follows:

Enter the Input filename
(enter in filename here)
Enter the Output filename
(enter in filename here)

If an absolute path is not specified then the output file is located
in the current working directory of the executable. The absolute path
for the output and input files may be specified also.
