Hi, I would like to build a program in C++ that (basically) retrieves
data from several websites and then displays the data in a particular
way.
I need some advice as to which functions / classes in the Standard
Library that might be suitable for this purpose.
So far, it has been suggested that the only way I could do this would be
by use of a third party library, that's written in C, namely Libcurl.
Is this sound advice or is there a 'pure' C++ way of doing this? (I'm
using unix system).
Thanks

No "direct" way to do that in C++, have a look at boost::asio

The C++ standard says nothing about networking. How networking is
handled is OS specific. In *nix you can look for the POSIX functions or
use a library like libcurl, which you mentioned or boost::asio which is
a OS independent C++ networking library. Libcurl also takes care of
Application Layer protocols whereas if you use boost::asio or POSIX
functions you have to implement that yourself. Simply fetching some
resources via http is reasonably straight forward though.

Have a nice day,
Stefan

It is sound advice, libcurl is the best tool for the job.
