I think both servers the same purpose. But, usually References are preferred over pointers as the reference can not be a NULL as like pointers. In some scenario pointers are the only solutions. Like the function which returns the object or NULL (specifying failure). But pointer isn't alternate solution for reference. Because you must have to make use of references while overloading an operator or providing an explicit copy constructor.

Additional to the links from the previous posters.... Rule of thumb: Use references when ever possible, pointers when necessary.
