array size

Hi all, this short paragraph of code is to get the user to enter q to quit. But why is the value of c = input_line[0] zero? What is the purpose of this line? Thanks!

Code:

---


char input_line[81];

          .
          .
          .


 if (file_in.eof())
            break;
        cout << "More? (Press 'Q' and ENTER to quit.)";
        cin.getline(input_line, 80);
        c = input_line[0];
        if (c == 'Q' || c == 'q')
            break;

input_line[0] is the first character in the array. It does not refer to the array's size.

If the value of input_line[0] is equal to "0", then your user is inputting "0".
