How can one use iostreams::filtering_streambuf to replace the
std::basic_streambuf used by cout.  I've tried the code in 1st
attachment; however, that code produces the output in 2nd attachment.
The desired output is shown in 3ird attachment.

How should the code be modified to get the desired output?

TIA.

-regards,
Larry
