listing 2: measurements — sorting a vector<string> (only main is shown; everything else is the same as in listing 1)

int main(int argc, const char** argv)

  if (argc != 2) {

    std::cerr << "usage: "

              << argv[0] << " <file>"

              << std::endl;

    return 1;

  }

  std::ifstream in(argv[1]);
