C++ string类型的split字符串分割函数

c++ string类型字符串分割，并返回vector。

std::vector<std::string> split(const  std::string& s, const std::string& delim)
{
    std::vector<std::string> elems;
    size_t pos = 0;
    size_t len = s.length();
    size_t delim_len = delim.length();
    if (delim_len == 0) return elems;
    while (pos < len)
    {
        int find_pos = s.find(delim, pos);
        if (find_pos < 0)
        {
            elems.push_back(s.substr(pos, len - pos));
            break;
        }
        elems.push_back(s.substr(pos, find_pos - pos));
        pos = find_pos + delim_len;
    }
    return elems;
}
