[EOF Problem] Extra Character In Output

I'm reading characters out of a text file and printing them to the console via this code:

Code:

---

ifstream textFile;
textFile.open(s.c_str(), ios::in);

char c = NULL;
while(!textFile.eof()) {
        textFile >> c;
        cout << c;
}

---

Here is what is actually in the text file:
1234567890

This is what gets printed:
12345678900


Why does it print the last character twice? What can I do to avoid it?

Read the FAQ on why you should not use eof() to control a loop like that (in fact, your observation is the answer why). Rather, use the result of textFile >> c.

Using eof is not a good way to control a file read loop. Just use operator >>

Code:

---

while(textFile>>c){
  cout<<c;
}

Awesome answers. Thank you both for your help.
