Problem with istream :: tellg ()?

Question

I read data.txt:

//////////////////////////////////////////////////

data.txt:

//////////////////////////////////////////////////

MissionImpossible3

Here is the code:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main() {
 ifstream fin("data.txt");
 string FilmName, ActorName;
 getline(fin,FilmName,'\n');
 cout << FilmName << endl;
//    cout << fin.tellg() << endl; //if I add this line to
// get current reading position of data.txt, the program just
// can't work as if tellg() triggered some error. So I removed
// all tellg(). What the reason for this and what shall I do
// if I want to get current reading position?
 int a;
 fin >> a;
 cout << a << endl;
// cout << fin.tellg() << endl;
 getline(fin,ActorName,'\n');
// cout << fin.tellg() << endl;
    for(int i=0;i<a;i++)
    {
     getline(fin,ActorName,'\n');
     cout << ActorName << endl;
//     cout << fin.tellg() << endl;
    }

 getchar();
}

Unexpected result:

I am using Dev-C ++ and Windows XP. I would appreciate it if you guys try to insert your results and the environment. There may be some problems with my system or compiler.
