I am not an expert .... and I just have some extra questions regarding the above code.
the "vote.h" , "color.h" etc. are they somewhere ? would u mind posting them as well ? or are they embedded in the microsoft window system ? (sorry ... i am not familiar with microsoft .....)

meow00 has a point: the problem is in the print routine for voter. I think I know what it is but the code would be nice to see.

It would also be nice to see the complete output from your PrintReport routine including the header (to see how things line up).

Hope to see more, -bcl

Bug is in the print function of the voter class.  I'm betting the issue is that you aren't using setw(...) before you enter the function, so the first element doesn't have its width specified, while all the other fields/lines following it do.

     for (int n = 0;n < size  ;n++)
    {
         
          voterlist[n].print(label);    
          label++;
    }
    cout << endl;

doh...forgot to include the important line.  here goes again ;)

cout << setw(5);
for (int n = 0; n size; n++)
{
    voterlist[n].print(label);
    label++;
}

As predicted, you use setw() AFTER you print an item. setw refers to the NEXT thing printed. You probably want to reverse each pair of items in print.

  cout << label          << setw(10)
          << idnumber     << setw(13)
 
becomes

  cout  << setw(10) << label
          << setw(13) << idnumber    
 
and so on.

Hi Experts,

    Excuse me again ! I happen to have 2 more questions here ..... I couldn't find any function called : OpenInput() and getche() in standard C++ book. Are they in some "window.h" file ? or certain special functions for microsoft ? since I have never seen them in Unix system .... I am wondering that whether  I  have missed any important things in my study or not .... Thanks a lot !

getche() just holds the screen -- its from conio.h
openinput  -- is from the filesutil file i made. used to read in data and write data to files.
