Ok my problem is i have a struct and im tring to ready a line into the struct using fstream. here is the code i have its just a basic layout of what will come later on. but here it is

(Toggle Plain Text)

// file: main.cpp
// author: Kyle Kjorsvik
// date: 8/31/04
// class: CSIS 352

// This is the file that contains the main function for assignment 1.

#include <iostream>
#include <fstream>
#include <string>
#include "date.h"
//#include "inout.h"
//#include "agecalc.h"
//#include "data.h"

using namespace std;

struct birthdate
{
    char name[];
    char bdate[];
};

int main()
{
    char chrName[25];
    int maxvalue = 10;
    birthdate bd[maxvalue + 1];
    int i = 0;

    ifstream inFile("data"); // input file
    if (inFile.fail())
    {
       cerr << "An error occurred. Unable to read input file." << endl;
        exit(1);
    }
    cout << "File opened" << endl;

    while(!inFile.eof())
    {
        inFile.get(bd[i].name[],25,",");
       //cout << bd[i].name << endl;
        ++i;
    }

    inFile.close();
    return 0;
}

and here is the file i am reading in

i need to read it in sperating the name and the birthdate. using the comma as the seperator. can someone help me on how i should be reading this into the array of structs? thanks

edit: if you need more info let me know

dont know exactly what i was doing wrong as i havent taken time to compare the code that i was give but here is what works

// file: main.cpp

#include <iostream>

//#include "data.h"

using namespace std;

struct birthdate{
  string name;
  string bdate;
};

int main() {
  const int maxvalue = 10;
  birthdate bd[maxvalue + 1];
  int i = 0, j;

  ifstream inFile("data");
  if (inFile.fail()) {
    cerr << "An error occurred. Unable to read input file." << endl;
    exit(1);
  }
  cout << "File opened" << endl;

  while(!inFile.eof() && i < maxvalue) {
    getline(inFile, bd[i].name, ',');
    getline(inFile, bd[i].bdate);
    ++i;
  }
  inFile.close();

  for (j=i-1; j>=0; j--){//print backwards for giggles
    cout << "\t" << bd[j].name << "\t" << bd[j].bdate << endl;
  }

  return 0;
}
