(转帖)C++中自己实现的split函数

由于太久远了，已经忘记作者是谁了，如果看到了，真的对不起，希望能给我留个言(我的QQ:543451622)

void split(const string& src, const string& separator, vector<string>& dest)
{
    string str = src;
    string substring;
    string::size_type start = 0, index;

    do
    {
        index = str.find_first_of(separator,start);
        if (index != string::npos)
        {    
            substring = str.substr(start,index-start);
            dest.push_back(substring);
            start = str.find_first_not_of(separator,index);
            if (start == string::npos) return;
        }
    }while(index != string::npos);
     
    //the last token
    substring = str.substr(start);
    dest.push_back(substring);
}
