Some good article on reference

Hi,

all can any one explain what is the exact difference between reference and pointer.

what is advavantage of using reference over pointer.

I have gone through some articles and books.

But I am not much clear about this concept.

What i feel is we can do everything with a pointer what ever can be done by a reference. so why there is a reference conecept .

If possible suggest me some good articles only on these topics.

Thanks
