How to load stack from CSV? C++

Question

I am trying to read a .CSV file and then put it into a stack the file contains data like this: id, name, date, num (The file has no header is for reference only)

-Example:

12, Mason, 08/12/2019, 58

10, Liam, 08/18/2018, 25

18, Ethan, 02/13/2020, 15

What I want is to take the first data from each row of the .CSV file and put it on the stack.

#include <iostream>
#include <fstream>
#include <string>
#include <conio.h>

using namespace std;

struct Node{
    int id;
    Node *next;
};

typedef Node *ptrNode;

void addstack( ptrNode *ptrtop, int n );
void printstack( ptrNode cursor );

int main(){

    ifstream in( "file.csv" );
    string s, t;
    Node *stack1 = NULL;
    int dat;

    while( !in.eof() ){
        getline( in, s );
        in >> dat;
        //getline( in, t );  //
            addstack( &stack1, dat );
            printstack( stack1 );
        }

    getch();

    return 0;
}

void addstack( ptrNode *ptrtop, int n ){

    ptrNode ptrnew;
    ptrnew = new Node;

    if ( ptrnew != NULL ) {
        ptrnew->id = n;
        ptrnew->next = *ptrtop;
        *ptrtop = ptrnew;
    }

    cout << "\tAdded: " << n << endl;

}

void printstack( ptrNode cursor )
{
    if( cursor == NULL ) {
        cout << "\n\tEmpty stack\n";
    } else {
        cout << "\tStack is: " ;

        while( cursor != NULL ) {
           cout << cursor->id << "->";
            cursor = cursor->next;
        }
        cout << "NULL\n\n";
    }
    cout << endl;
}

consider the CSV file as a text file and read it as usual.

1. Read each line.
2. Split each line on the basis of comma character into an array.
3. Put the first item of the array on to the stack.
