    // I don't recommend using the std namespace in production code.
    // For ease of reading here.
    using namespace std;
    // You could also take an existing vector as a parameter.
    vector<string> split(string str, char delimiter) {
      vector<string> internal;
      stringstream ss(str); // Turn the string into a stream.
      string tok;
      while(getline(ss, tok, delimiter)) {
      return internal;
    int main(int argc, char **argv) {
      string myCSV = "one,two,three,four";
      vector<string> sep = split(myCSV, ',');
      // If using C++11 (which I recommend)
      /* for(string t : sep)
       *  cout << t << endl;
      for(int i = 0; i < sep.size(); ++i)
        cout << sep[i] << endl;
