have look at the tutorial
http://www.cplusplus...l/pointers.html

there is a section on arrays and pointers

[Bench]

Here's a few good quality links on the subject of pointers

Pointers in C are used for all kinds of things:
1. For linked data structures (like linked lists, binary search trees, AVL trees, you name it).
2. To save memory (pointers take up much less space than the possibly large objects they point at).
3. For generic programming (like what templates do for C++).

Read up on the tutorials other gave you and see what you can do.

Quick tip: it's sometimes useful to check the date of a question. If veerendranadh.killampalli is still stumped on pointers, it's probably not going to work out.

You are right, I did not even notice the date.

But it sure seems in all that time, he should have gotten SOME kind of reply!
