   double netPay;
   netPay = calcNet(&emp);    // pass an address
   cout << setw(10) << setiosflags(ios::fixed) << setiosflags(ios::showpoint) << setprecision(2);
   cout << "The net pay for employee " << emp.id << " is $" << netPay << endl;
   return 0;
}
double calcNet(Employee *pt)   // pt is a pointer to a
