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!

Answer 1

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.

• Objective C Resources
• The Definitive C++ Book Guide and List
• The Definitive C Book Guide and List

Answer 2

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.

Answer 3

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

Answer 4

i always liked this one:

and of course this faq

Answer 5

about pointer:

Pointers on C by Kenneth Reek

Answer 6

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.
