c++ - Splitting a string

Question

I have this code to split a string. For some reason, it just sits there doing nothing. I am not sure what the problem is. By the way, delim = ' ' here.

vector<string> split( const string &str, const char &delim )
{
    typedef string::const_iterator iter;

    iter beg = str.begin();

    vector<string> tokens;

    while(beg != str.end())
    {
        iter temp = find(beg, str.end(), delim);
        if(beg != str.end())
            tokens.push_back(string(beg, temp));
        beg = temp;
    }

    return tokens;
}

Here is another nice and short Boost-based version that uses a whole string as delimiter:

std::vector<std::string> result;
boost::iter_split(result, str, boost::first_finder(delim));

Or case-insensitive:

std::vector<std::string> result;
boost::iter_split(result, str, 
    boost::first_finder(delim, boost::is_iequal()));
