Where are the best explanations of variables, pointers, references and memory addresses on the net?

Question

Although I think that I've got that now (the light bulb is pretty bright now but still flickering a little bit), I'd like to read more stuff about pointers, variables, references, memory addresses, etc. Just the whole thing, i.e. what I have to understand when hearing thre term "reference" (think it's just a pointer, not sure).

So let us know your sources! Great articles, books, PDF's, videos, whatever. Anything is appreciated.

Thanks!

I would have sworn this was a duplicate, but I can't find it. Good question. — dmckee --- ex-moderator kitten, Apr 29 '09 at 18:22

Pointers, References, and Arrays in C++ has a wonderful explanation of the basics.

Help yourself with a book. A good one is "The Objective-C Programming Language" from Apple. It is well written and free:

Also, see:

"Programming in Objective-C" by Stephen Kochan
"Learning Cocoa with Objective-C" by James Duncan

As for C and C++ resources: these have been discussed before on SO -- try searching the site.

What I found the most confusing is the difference between an array and a pointer in C. Here's the C FAQ which finally explained that to me.

Read here the whole FAQ about pointers and arrays.

that book isn't specifically about pointers, but is about the C language. The title is a pun. However, it is a great book :-). – user83255 May 05 '09 at 14:34
I was going to recommend this book if only for the fact that the author used to be an integral member of my schools CS department. I often use header files with his name on them. ;) – Mr. Shickadance May 18 '09 at 13:23
"used to be an integral member of my schools CS department." It must really suck to have CS departments with fractional members ;-) – Jonas Kölker May 18 '09 at 13:53

This has to be the most articulate & awesome pointer tutorial & reference i have ever come across.

http://cslibrary.stanford.edu/

It does not assume any pre-requisites & it slowly builds from the basics to most advanced topics & has lots of code & sample problems too.

Thanks Nick Parlante for this awesome resource.

Lots of other useful resources are available at http://www-cs-faculty.stanford.edu/~nick/

I'm studying engineering and we had this little crash course in C and went through this book called "How to program C" by Deitel. It covers all the basics and has a few code samples in it.

However; Pointers can be tricky to get, especially from only reading about them. I strongly recommend this lecture by Richard Buckland about pointers.

Then of course, just start experimenting. It is the best way to learn this subject.
