  The advantage of the C++-way is that a std::string is more secure
(forget about memory leaks) and its syntax is simpler.

  std::stringstream is for that.

  std::stringstream works like a std::ostream (and like a std::istream)
but instead of outputting to a file it stores things given to it onto
memory as a string. You can then get that string from it.

  Since std::stringstream is inherited from std::basic_iostream, you
can use it anywhere a std::istream or a std::ostream is expected.
