Description

  ostringstream class provides an interface to manipulate strings as if they were output streams.
  The objects of this class mantain internally a pointer to a stringbuf object that can be obtained/modified by calling member rdbuf. This streambuf-derived object stores a sequence of characters (string) that can be obtained/modified by calling member str.
