Find a word in string and extract int

[ACE123]

Hi. i'm working on a login program that stores usernames/passwords in files. once the user logs in, the program opens a CSV file and searches for the entered username and extracts the (int) privilege associated with that user e.g. 1/2/3.

I can read the CSV file into the program, but how do I find the specific username, then extract the int.

#include <iostream>
#include <fstream>
#include <stdio.h>
#include <string.h>
#include <sstream>
using namespace std;


int main()
{
    int privilege;
    char filename [80];
    string line;
    string pass;

    cout << "Username: ";
    cin >> filename;
    cout << "Password: ";
    cin >> pass;
    ifstream myfile (filename);
    if (myfile.is_open())
    {
    while ( myfile.good() )
    {
      getline (myfile,line);
      if (pass == line)
      {
        fstream MyExcelFile ("Users.csv", ios::in | ios::out | ios::app);
        string Value;
        while (MyExcelFile.good() )
        {
        getline (MyExcelFile, Value, '\t');
        cout << Value;
        cout << "\n";

      }


    }
    myfile.close();
    return 0;
}}}

while(getline(fileType, string)
{
     if(!isnum(line.c_str());
          username = line
}

Hi Aramil,
could you please explain how this code fits into mine. I'm not sure what you mean by (filetype, string)
But thanks for your quick reply.
