random quote generator

I was wondering what everyone thought of writing a random quote generator in C++ for XP/Vista.  I'm having a hard time with it.  I wanted it not to have a regular GUI, just have a system tray icon that would pop up a message bubble with the random quote from a .txt file, say every hour or so.  I think I figured out the bubble thing, but getting the program to take a random quote from the text file is driving me crazy.  Do I have to make the quotes in separate strings in the code of the program, so I can get them to pop up every hour in a bubble window?


std::string get_random_quote() {
  std::vector<std::string> quotes;
  std::istream in("reddwarf.txt"); //Available on demand
  in.exceptions(std::ios::failbit | std::ios::badbit);
  while(in) {
    std::string line;
    std::getline(in, line);
    //do some sort of trim() thing here if you like
    if(line.size() > 0)
      quotes.push_back(line);
  }
  //float->int truncates
  int idx = int(float(std::rand())/RAND_MAX*quotes.size());
  return quotes.at(idx);
}

Not really tested.

You could do all sorts of optimisations and crap, but honestly, who cares? It's happening once an hour, it doesn't need to be OMG OPTIMIZED.
