  5: int main(int argc, char* argv[])
  6: {
 *7:    const int Dividend = 6;
 *8:    const int Divisor = 2;
 *9:
*10:   int Result = (Dividend/Divisor);
*11:   Result = Result + 3;// Result is now its old value+3=6
*12:
*13:   cout << Result << endl;
 14:
 15:    // Note: You must type something before the Enter key
 16:    char StopCharacter;
 17:    cout << endl << "Press a key and \"Enter\": ";
 18:    cin >> StopCharacter;
