C++ PROGRAM

Process command line arguments

just add additional code to my program with the ff:

* Should have command line mode in the main (the interactive mode is already done)

* write a code to accept filenames on the command line and read its byte

* allow drag and drop (the user could simply drag the file to the reader)
