They're not confusing at all.

My antivirus started to ring bells with that link.
Just in case, don't visit it.

weird, it passed out over zealous web nanny on my office computer.
I removed the link and put the wikipedia link instead.

I suppose it was a google ad or similar...
they don't necessarily have to be the same for you as for me or when you took the link as to when I visited the site.

I thought about that pointer, yesterday, but thought it would destroy the tattered remains of my reputation. Perhaps that is why you can use a pointer to fetch data.

The most famous pointer of them all is ... Google.
How?
Well, given a search string, Google points us to the location(s), meaning website(s), where that search string is present. Agree?

I'd say the links it returns are the pointers, but you do you.

So is Google a pointer factory, or a pointer dictionary?

How hard can a pointer be? It points to a chunk of memory with stuff in it. Keep that fundamental concept in mind at all times and you shouldn't have any problems.

I remember learning pointers being a real "light bulb" type of learning experience for me.
I felt like I was banging my head against a wall trying to figure them out, then with a single revelation, they suddenly made complete sense to me. I've never been able to figure out what caused that revelation.

I've had several of those epiphanies in development over the years. Like when I finally understood COM on its terms (a binary vtbl based contract)
I really enjoy them. I can't remember if pointers was one because it was so long ago.

I know what you mean, but my "pointer epiphany" was memorable enough to still be clear to me more than 30 years later... now if I could just remember where I put my glasses.

the C abstract machine
there is no problem with pointers if you look straight at them. the problem is when somebody tries to wrap them in some obscured "politically correct" story that doesn't hurt a chipmunk if you step on it.
i know this line is confusing, but Pascal was my first programing language and when the time came to grow up and use pointers normally i reached for a Pascal programming book...
well, that book in it's chapter of pointers had everything else, about lists, about binary trees... but i could not tell what pointers are.
i mean, the person who wrote that book constantly repeated how pointers are really useful although you should avoid to use them as much as possible... he doesn't know about pointers.
then i read a chapter about pointers from a C tutorial and everything became crystal clear. there was i happy and using pointers in Pascal.
the same thing was with win32 programming. you can not learn it from a Delphi book, you need a C book for that. but you can sure as hell do that in Pascal as good (or better) as in C if you learn the right way.
pointers are a fundamental thing. the 8086 processor has a few general purpose registers and about the same number of Index registers. out of this bunch SI and DI are your pointers.
and i bet you will understand pointers even better if you learn assembly than C, but C is good enough.

I first used pointers in asm, because it was the first thing other than basic i could really write code in for the 6502. I learned C later. I'm fine with them. it seems many other people aren't, hence the idea for the article.

yeah, i was on the 6502 too. the most close to pointers out of the top of my head was this addressing mode like: lda ($fb),y or lda ($fb,x)
hell, i don't even remember was there a comma or a dot in front of the index register. much less how these two modes were called.
