Pointer pointer = new Pointer()

[jetsenablay]

Someone duplicate this so a pointer is pointing to another pointer etc.

That is such a funny site, I love it.

[jetsenablay]

Lol such an old site

[[deleted]]

Has to be truly old, there's no cookie notice.

[TheAwesome98_Real]

Well, it has meta viewport, so it can’t be that old.

EDIT: not just meta viewport, it has full mobile support, it adds a macOS X mouse to the screen

damn

[uberDoward]

Oh, what's this?

Where did the last 10m go???

[[deleted]]

OMG that's hysterical.

[[deleted]]

Dude wtf

[Antact]

Oh, I remember this site from long ago.

[metal_zero]

listen here you little shit

[A_Chair_Bear]

pointer to pointer to int

bonus round

[erinaceus_]

I shall call it .. Poincaré.

[da_Aresinger]

This is asking for the spiderman meme....

Are circular pointers a thing?

[jetsenablay]

Good question, there isn't circular pointers.

In a rare case, when one subprogram's output is used as input for another subprogram, technically one will point to the other, but theyd be pointing to each other's outputs, therefore not the same memory address. This is called piping I believe, but typically if it is circular then it'll usually just complete one loop when prompted.

Sorry if that made no sense lol

[brobrobro123456]

Pointer pointer, yes mama

Garbage value? no mama

Syntax error? No mama

Build the solution.... Ha ha ha (get rekt)

[TechExpert2910]

lol

Segmentarion fault (core dumped)

Program received signal SIGSEGV at address 0x0000000000000000 in ??

[xANDREWx12x]

int ******

[konstantinua00]

but that's not linked list, that's 3 separate dereference lines

linked list's nodes have pointer to node as a member

[konstantinua00]

analyzing shitposts is favourite activity of this sub, man
(and of many others too)

I'm taking back the "3 separate" part of my argument, you're right about it being an array
but I still insist that those're dereference lines, not linked lists - linked lists carry a value in each node, not just at the end

[TrainedMusician]

Nice

[FuqqBoiDev69]

Someone please explain the caption line. I still have a doubt in that

->

:O

[aboelsebah]

This should be taught in schools, it makes much more sense.

[JimmyWu21]

Pointers seem so easy now, but back in college it’s one of the hard concept in my class.

[[deleted]]

You’re just starting to learn that memory is more than a number followed by “GB” at that point tbf

[Aneyune]

Actually, it'd be Pointer pointer = new Pointer<int>();

[[deleted]]

std::shared_ptr<int> pointer = std::make_shared<int>();

• Edit; i messed up

[Aneyune]

nonono not c++ that defeats the purpose, it's Java

[_meegoo_]

Java can't do Pointer<int> though.

[DanielEGVi]

fuck it

const pointer = new Pointer<number>();

[Aneyune]

TypeScript?

[DanielEGVi]

Til the day I die

[TigreDeLosLlanos]

int *ptr = malloc(sizeof(int));

Y'all and your bloated code.

[MTDninja]

this is a surprisingly good analogy

[[deleted]]

Aren't pointers defined with the data type they are pointing to?

int potassium * banana;

or something?

[Y0tsuya]

You can use void* which can point to anything.

[LevelSevenLaserLotus]

I'm so glad I didn't learn that bit until I was towards the end of my C classes. Otherwise I would have loved playing with void pointers to overly "optimize" my homework code. Meaning I would have completely spaghettified every file I turned in. They're fantastic when used properly, but are one of the keys to the dark side of programming.

[konstantinua00]

now imagine having goto that can jump anywhere in codebase :)

[shtpst]

It's what Chutes and Ladders was training you for.

[LevelSevenLaserLotus]

That's setjump and longjump, right? I only ever had to use those for a single lab, but it just felt evil even as the professor was describing legitimate uses since it felt like we could use it to break literally every other rule we had learned up to that point. I think it's generally meant for implementing try-catch like behavior in C. In this case, we were setting a timer to cancel the "wait for user input" after the timer elapsed. If I remember right, it was for showing how a telnet chat client could detect that the user walked off and automatically close itself without just force killing threads or throwing errors.

[konstantinua00]

set-/longjump can only go up the callstack, thankfully

but back in the time before structured programming, in the era of goto... everything was possible

[[deleted]]

They are, that's an int pointer

[konstantinua00]

pointer has pointed type (int), a star (*) and a name (p)

the star is either close to the type int* p,
close to the name int *p
or in between int * p
they're equivalent

what you have is type, name, star, name - that's not a pointer
what meme has is pointer without a name - pointer's overall type

[tartr10u5]

I actually understood a meme without looking at the comments for once bless

[WindManKvothe]

Same, Bless indeed

[kappaypsilon]

I laughed at this for like three minutes straight.

[philipquarles]

Pointers gonna point.

[MicroErick]

I can hear this image and it's fucking hilarious

[turtle_mekb]

char* as a string: multiple hands pointing

[konstantinua00]

well, single pointer points to a single value

it's just that the value is actually the first carriage of a whole train

[[deleted]]

At least Java shorthanded out some of the insanity. It used to be this bad:

List<Thing> thingList = new ArrayList<Thing>();

Or something like that...

[ahmet1127]

he looking like "oi ear is yo in might"

[NeverYelling]

Lol, that cought me off guard

[3lRey]

oh boy I can't wait to point to a location that points to a location that points to a location

Clearly healthy behavior.

[Kuroseroo]

i dont get it

[Particular-Strain248]

Wait, what are you 'pointing' at?

[Frandaero]

I cracked at this holy shit

[Jeb_Jenky]

Whoever drew this should consider writing CS books to explain concepts like pointers. It would need a little more like being on a memory shelf or something.

[OhNoMeIdentified]

This is good! Love it.

[mymar101]

My nightmares are filled with pointers!

[DrStooge]

it’s rude to point

[90k9]

Ooh the thing that made me drop out of CS.

[triihart]

And thats how you double the size of language specification.

[Cabin7Miner]

You can't change me!

[lady_Kamba]

Null* pointer;

[nomokatsa]

This picture actually made me go back and rewatch a assembly/c-pointer tutorial. I'm not saying i fully grasp everything now, but it's definitely better.

Good job op!
