How do i seperate my text file values to store in a vector

I have a file.txt with values such as

DOB,NAME,Arrival,Depature
12/04/2021,Dennis,12:30:20,14:30:40
10/03/2001,Sam,14:20:30,-

I want to store these values in a vector I have figured out how to store all of them in the vector but now i am creating another vector where i want to store all the values without a depature time so in this case Sam '-' which has this value. and another vector which will store Dennis which already has a depature time

What i have done so far

name *v = new name;
    ifstream myFileStream("FILE.txt");
    if(!myFileStream.is_open()){
        cout<<"File Failed to open"<<endl;
    }
    string date,name,arrival,depature;
std::string delimiter = "/";
std::string delimiters = ":";


    string line;
    string b;
    string c;
    string d;
    string e;
    std::getline(myFileStream,line);
    while(getline(myFileStream,line)){
        stringstream ss(line);
        getline(ss,date,',');
        //veh.at(i).dt = v->dt;
        size_t pos = 0;
        std::string token;
        while ((pos = date.find(delimiter)) != std::string::npos) {
            c=token;
            token = date.substr(0, pos);
            b=token;

            date.erase(0, pos   delimiter.length());

        }
        v->dt.year = stoi(date);
        v->dt.month = stoi(b);
        v->dt.day = stoi(c);
        veh.at(i).dt.month = v->dt.month;
        veh.at(i).dt.year = v->dt.year;
        veh.at(i).dt.day = v->dt.day;
        getline(ss,v->name,',');
        veh.at(i).pltno = v->name;
        getline(ss,arrival,',');
         size_t pose = 0;
        std::string tokens;
        while ((pose = arrival.find(delimiters)) != std::string::npos) {
            e=tokens;
            tokens = arrival.substr(0, pose);
            std::cout << tokens << std::endl;
            d=tokens;

            arrival.erase(0, pose   delimiters.length());
        }
         v->arrive.hh = stoi(e);
        veh.at(i).arrive.hh = v->arrive.hh;
        v->arrive.mm = stoi(d);
        veh.at(i).arrive.mm = v->arrive.mm;
        ((stoi(arrival) <= 9) ? 0 : "");
        v->arrive.ss = stoi(arrival);
        veh.at(i).arrive.ss = v->arrive.ss;
        //veh.at(i).arrive = arrival;
        getline(ss,depature,',');
        //cout<<veh.at(i).arrive<<endl;
        i  ;
    }
    myFileStream.close();

Please guys i really need help with this I am stuck at the moment and really would appreciate someone helping me with the code so far the code above stores the Name arrival DOB into the vector but I am going to create a new vector for people who left and people who have not how can i seperate values which have '-' & which have time and store it in a similar format?

Thank YOU
