            cout<<"\nthe sorted elements are: ";

            for(p=&a[0];p<=&a[n-1];p++)

            {

                        cout<<*p<<" ";

            }

            getch();

}

           

Output:

enter the no of elements: 8

enter the elements-

-1 0 9 99 -45 5 6 3

the sorted elements are: 99 9 6 5 3 0 -1 -45
