Thank you for your reply. Yes, I think that the reflect() will be called
when I run the program. Why this is not right? I do modify what should be
changed and build the project without error. I define an "ofstream" object
"output" by
ofstream output("C:\\out.dat"); and run the program, but no out.dat formed.

Thank you for your assistant.
