This is my assignment, not sure what my professor really is asking for,

Your assignment is to add optional file input and output functionality to the utility program ExtractDesign.
The functionality must remain the same with the exception that input or output may be optionally redirected to files and your program shall conform to the Homework Submission Requirements.
The program shall attempt to read an input file name until the file opens successfully.
(Microsoft states that the maximum length of Windows file names is 255 characters.)
An exception is that if the file name entered is blank, then input shall be from standard (default) input as it does now.
The program shall attempt to read an output file name until the file opens successfully.
An exception is that if the file name entered is blank, then output shall be to standard (default) output as it does now.
