  p= new (nothrow) int[nums];
  if (p == 0)
    cout << "Error! memory could not be allocated";
  else
  {
    for (int i =0; i < nums; i++)
    {
     cout << "Enter number: ";
     cin >> p[i];
    }
    cout<<endl;
    cout << "You have entered: \n ";
    for (int i =0; i <nums; i++)
    cout <<endl<< p[i];
    delete[] p;
  }
  return 0;
}
