    Well...

    Your algorithm for swapping seems okay, but you are not coding it properly. I think the others already presented the correct codes for you. You should try them and tell the difference between what you did and how the others did it. You can't learn if you don't analyze the problem.

    Okay how about this:

    In order to swap the values, you should not dereference the variables.

    int *a, *b, *c;

    what you did was like this: c = a; you are swapping the addresses but not necessarily the values. You should have done this *c = *a; this way you will surely get what you want.

    I'm not sure if I have explained this quite accurately, but I'm sure this is the main idea.

    We have - study the first post from The Dog

    If you want to output inside the swap function, try
    cout << "new value of a is " << *a << endl;
