Hi Guys,

What don't you understand after googling each topic?
Can you be more specific about your problem?
I think that copying a whole book chapter as an answer of this unspecific question doesn't help you.

Why don't you write a small program trying out how a stack works and then come back to us if you are stuck, showing us what you have written so far?
