Parsing a comma-delimited std::string [duplicate]

Answer 1

bool GetList (const std::string& src, std::vector& res)
  {
    using boost::lexical_cast;
    using boost::bad_lexical_cast;
    bool success = true;
    typedef boost::tokenizer > tokenizer;
    boost::char_separator sepa(",");
    tokenizer tokens(src, sepa);
    for (tokenizer::iterator tok_iter = tokens.begin(); 
         tok_iter != tokens.end(); ++tok_iter) {
      try {
        res.push_back(lexical_cast(*tok_iter));
      }
      catch (bad_lexical_cast &) {
        success = false;
      }
    }
    return success;
  }
