getch and EOF

I'm testing this function:

Code:

---

string ucitaj (int n)
{
        string str;
        int i = 0;
        int ch;

        while ( ((ch = getch()) != EOF))
        {
                if ((ch == 0) && (i > 0))
                {
                        getch();
                        i--;
                }
                if (isdigit(ch))
                {
                        cout<<static_cast < char > (ch);
                        str += ch;
                        i++;
                }
                if ( (ch == '\b') && (i > 0))
                {
                        cout<<"\b \b";
                        i--;
                }
                if ( i == n)
                {
                        break;
                }
        }
        return str;
}

I'm entering characters from keyboard and I noticed that Ctrl-Z (EOF under windows) simply doesn't work, which I expected because of that line with ch == 0.
My question is how to enable that loop quit after user press Ctrl-Z?
Thanks

Maybe this way.

Code:

---

while ( ((ch = getch()) != 26))
