how to read txt files in unknown folders |
hi, all
I am given a root folder, there are sub-folder and sub-sub-...folders
under the root folders. There are also many txt files at any level of
the folders. How can I automatically visit all those txt files? The
structure of the folder tree is unknown. Thanks for help. I am using
gnu c++.

ISO/IEC 14882:2003 does not discuss filesystems. You need to ask in a
group dedicated to your platform/OS. Alternatively, Boost may have
something (http://www.boost.org).

Boost::filesystem has a director_iterator, and a possibility to
ask whether a given path is a directory or not. Given that,
it's trivial to write a recursive function which visits all
sub-directories.
