ifstream's tellg() is unreliable

[lidgaj]

Hello, I have a text file (test.txt), the contents of which are

a

b
c
d
e

The program looks like this:

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ifstream a("test.txt");
    string x;
    a >> x;
    cout << x << endl;
    a >> x;
    cout << x << endl;
    a.seekg(a.tellg()); // Problem lies here.
    a >> x;
    cout << x << endl;
    a >> x;
    cout << x << endl;
    return 0;
}

If the a.seekg(a.tellg()) is present, the output is

a
b
d
e

However, if I get rid of it, the output is

a
b
c
d

Is there a more reliable way to use tellg and seekg, or am I using the wrong methods? If I save the tellg value to a variable and later use it in seekg to come back, it also doesn't go to the correct position.

You need to open it as binary http://www.cplusplus.com/reference/iostream/ifstream/open/

otherwise line endings are automatically converted (Win \r\n -> \n)

Thank you.
