The C++ String Toolkit Library (StrTk) has the following solution to your problem:

#include 
#include 
#include 
#include "strtk.hpp"

int main()
{
   std::deque word_list;
   strtk::for_each_line("data.txt",
                        [&word_list](const std::string& line)
                        {
                           const std::string delimiters = "\t\r\n ,,.;:'\""
                                                          "!@#$%^&*_-=+`~/\\"
                                                          "()[]{}<>";
                           strtk::parse(line,delimiters,word_list);
                        });

   std::cout << strtk::join(" ",word_list) << std::endl;

   return 0;
}
