I need to enter an employee number that must be 9 digits, no more and no
less. The way I am doing it here seems overly complicated, and does not
work anyway. I need to move on to other parts of the program now. Can
anyone tell me a quick easy way to verify length of data entry?

Here is my function:

void employee_nbr_entry(employee& e)
{

//this can't be too long or too short.

 char test_nbr[9] = "        ";

 char ch = ' ';

 int count = 0;

 cout << "Enter 9 integer employee number: ";

 for (int i = 0; i < worker_nbr; ++i)
 {
  ch = getchar();
  cout << "int(ch) is: " << int(ch) << endl;

  test_nbr[i] = ch;

  ++count;

  if (count > worker_nbr)
  {
   if ((int(ch) == 10))
   {
    cout << endl << "nbr limited to 9 characters";
    test_nbr[i] = ch;
    e.nbr = atol(test_nbr);
    return;
   }
  }

  if ((int(ch) == 10))
  {
   if (count < worker_nbr)
   {
    cout << "must be at least 9 characters" << endl;
    cout << "enter 9 digits from scratch: " << endl;
    employee_nbr_entry(e);
   }
  }

  e.nbr = atol(test_nbr);
 }



 return;
}


I know there must be an easier way to do this. Any hints appreciated.

John
