.dat I/O not loading variables

Ok I tried putting in a load/save feature into my program, so I don't have to re-enter all the data over again. So I added the following functions:

Code:

#include <iostream>
#include <stdlib.h>
#include <wincon.h>
#include <conio.h>
#include <windows.h>
#include <fstream>
#include "gkinfo.h"
using namespace std;

void savestats(student &x, course* c)
{
    clrscr();
    ofstream save;
    save.open("stats.dat");
    cout<<"Saving statistics...";
    save.open("stats.dat");
    int i;
    /*Save variables*/
    save<<x.FNAME<<endl;    //Firstname
    save<<x.LNAME<<endl;    //Lastname
    save<<x.ID<<endl;       //Student ID
    /*Course variable save*/
    for(i=1; i<25; i++)
    {
        save<<c[i].cGrade<<endl;        //Grade
        save<<c[i].CourseName<<endl;    //Course Name
        save<<c[i].nCurrentPoints<<endl; //Current poits in class
        save<<c[i].nMaxPoints<<endl;     //Max points you got
        save<<c[i].nHour<<endl;         //Hour of class
    }
    save.close();   //close the file
    cout<<"Stats saved!";
}

void loadstats(student &x, course* c)
{
    clrscr();
    ifstream load;
    load.open("stats.dat");
    cout<<"Loading statistics...";
    int j;
    /* load vars*/
    load>>x.FNAME;  //First Name
    cout<<x.FNAME;
    load>>x.LNAME;  //LastName
    load>>x.ID;     //ID
    for (j=1; j<25; j++)
    {
        load>>c[j].cGrade;
        load>>c[j].CourseName;
        load>>c[j].nCurrentPoints;
        load>>c[j].nMaxPoints;
        load>>c[j].nHour;
    }
    load.close();
    cout<<"Stats opened!";
    cin.get();
}

Now the problem is, when I have it spit out the variable x.FNAME, it spits out the name of the variable I entered after I had saved. So say I had saved it when x.FNAME==BFGH. Ok, so then after saving I'll make a new name, and set x.FNAME==HGFB. Well when I load the file, x.FNAME still equals HGFB, and not BFGH like I had it saved to. I don't understand why it is doing this. I thought that the ifstream opened up for loading the variables? Does anybody know why it is doing this?


*NOTE: Sorry for asking so many questions *

EDIT: I'm such an idiot, I had save.open() twice, causing the error. Let that be a lesson to everybody: Don't double call

Wow though, thats is indeed quite undefined behavior. I'll get bashed for saying this on the C++ board, but this is precisely why I use the C standard functions for file IO.
