I was recently talking with a good friend of mine about how she likes PHP over C++ because of it's ease of usability. In this case, string manipulation. C++ doesn't have a split functio nto split strings by a deliminator, which PHP does, so it's handy. In discussing with her various ways of accomplishing such a task, I decided to write a small function to do it.

Now I know there are those of you out there who will look at this code and see fifty better ways of doing it, or some will look at it and say "There's already a way of doing that," or will look at it and say "That's not very optimized." Or any other plethora of things. But, I don't care. It wasn't written to be optimized, I didn't write it the best way possible, or anything like that, simply because I'm not the best. I'm a mediocre programmer who was just doing this as a test for myself to see if I could successfully write a split function for strings. So without further ado, here it is.

EDIT: I just noticed there was some old code that doesn't need to be there. It's better now.



I know, not the most glamorous, but it works wonderfully.

The outcome on her progress getting it done is, she got her own code working without having to look at mine. Her project is well off on it's way and I'm quite proud of her for what she's been able to accomplish thus far. She's learning quite well. :-)

void Tokenize (const std::string& in, std::vector<std::string>& out, const std::string& delim)
{
    out.clear();

    size_t tokenPos = in.find_first_not_of(delim);
    size_t delimPos = in.find_first_of(delim, tokenPos);
    while(tokenPos != std::string::npos)
    {
        out.push_back(in.substr(tokenPos, delimPos - tokenPos));
        tokenPos = in.find_first_not_of(delim, delimPos);
        delimPos = in.find_first_of(delim, tokenPos);
    }
}
