Correct syntax for for using getline with vectors?

[Ulnarian]

I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error. Does anyone know the correct way to go about this?

Thanks!

#include <iostream>
#include <fstream>
#include <vector>
#include <string>

using namespace std;

vector <string> v_input;

int main()

{
    ofstream fout ("Insert File Path Here.txt");
    fout << "4, 8, 15, 16, 23, 42";
    fout.close();
    
    ifstream getdata ("Insert File Path Here.txt");
    
    while(!getdata.eof())
    getline(getdata, v_input.push_back(), ','); //read comma separated values into a vector--problem line!
    
    ifstream.close();
    
    return 0;
)
