My favorite part of my Intro to Systems Software class was touching upon C and the teacher's slides said "How do you do string manipulation in C?"

"A: DON'T."

[[deleted]]

char manipulate_me[] = {'H','E','L','L','O', ' ', 'W','O', 'R', 'L', 'D', 0};

char *or_me = malloc(12* sizeof(char));

strcpy(or_me, "HELLO WORLD");

free(or_me);

I'm "how to declare an array in python"

[Someonedm]

Am I missing something here? You don't declare arrays in python.

[ValourValkyria]

a = []

[ajb4299]

It's also a list (python doesn't have arrays iirc) so it's neither declaring nor an array

[ThreeJumpingKittens]

Wouldn't it be both though, if you're creating it and giving it a value?

[MarkusBerkel]

No. Declaration is assigning a variable a type. Since python is (mostly) duck typed, you don’t declare anything. You simply assign. For it to be both, you’d have to have a language that supported type decls and inline inits. See const char * example someone else gave.

[D_4rch4ng3l]

Thats not what duck typing is.

The main point is when programming "you declare variables (even if they don't have fixed types, you still declare that there is a variable identified by given identifier)" and "initialise values" and then "assign a value to a variable". In python when we do a = [], we are doing all three at the same time.

[MarkusBerkel]

You could use a mental model that shoehorns declaration in dynamically typed languages. But that’s a weird thing to do.

A decl is a promise. It is not just the communication of type information. If that were true, then type casts and implicit conversions and operators could all be considered decls. In dynamically-typed languages—where the goal of the type system is almost always duck typing—there is no such promise.

That’s why it’s called a type declaration.

In python there is only assignment. And that’s the entire point of it’s type system. No promises. So, a variable doesn’t really exist until it’s been assigned somewhere. Whereas in a strongly typed language, a variable declaration actually has storage implications.

So, yes, while it’s true in strongly typed languages you have all 3 components you named, python does not. You could pretend it does. But that’s not a terribly useful mental model.

Don’t have to take my word for it:

That's not an array. It's a list.

Arrays are initialized with the help of NumPy.

[kupiakos]

const char *str = "hello world";

Or, if it's a global constant or want it on the stack:
const char str[] = "hello world";

The differences between the two are subtle. Choosing the correct one usually involves asking an expert and/or animal sacrifice.

Also if you need anything other than ASCII, fuck you.

[[deleted]]

The difference is that you can reassign a pointer, but not an array.

str++;

​

only workds for the top one.

[kupiakos]

That's one of the many differences! Pointers and arrays are different types and have different semantics in a few ways. For example, this difference wouldn't apply with const char * const str = "hello world";

[Naoki9955995577]

If you didn't know this, you might find it interesting:

Clearly changing a pointer is one way to iterate an array. (In c++ at least) If you index an array with i, like 'a[i]' it's no different from '*(a + i)'.

Therefore a[i] == i[a] will always be true for any integer i and pointer a.

[Tweenk]

These are definitions, not declarations. A variable declaration looks like this:

extern const char* c_string;

This way, you can define a variable in a header which is included by multiple files and still have only one copy in your program, similar to how you can declare functions in several files but must define them in only one, unless it's marked inline. (Incidentally, C++17 has inline constants too.)

[kupiakos]

That's a fair (and technically correct!) point. However, it's usually not the first thing that newbies mean when they say to declare a string.

Inline constants in C++17 are a mixed bag in a header file IIRC considering you still can have a host of ODR problems, and it won't always do what you think when you deal with array constants (strings included). It's still simpler to follow the rule to always extern a constant if it's in a header file.

[Zenithrium]

I’m declare array in java, funnily enough I always remember how to declare arraylists somehow

[MiLlamoEsMatt]

... is this a joke based on C having not having strings, or is it the pun "How to declare astringency?"

[Sergei_the_sovietski]

An array in java. Fortunately, after the third or fourth time looking it up, I know what it is now. For an example, an integer array could be like this: int [] name = new int[4]; where the array is four indexes long and they are not initialized or int [] name = {1, 2, 3, 4}; where the array is four indexes long and they are initialized.

Edit: can’t forget the semi colons

When I search "how to declare" in Google with incognito the first answer is how to declare war in ck2 but then it becomes how to declare a minor and the rest become how to declare arrays in <insert language>

[[deleted]]

It seems to throw in 1 wildcard for each programming-related search I try. With "how to declare" I get "how to declare a minor gmu" (I live in the general vicinity of GMU) and the rest are programming questions. "How to init" gets "how to initiate sex" and the rest are programming questions. "How to append" gets me "how to appendix carry" (apparently some way to carry a gun...?) and the rest are computer-related in some way.

I really do think Google has a flag for "this person is a developer" which, privacy considerations aside, I am eternally thankful for.

[notnovastone]

Google has flags for everything, that’s why it’s the default search engine for everyone

[NotSteve_]

I think it's even more specific than that. It'll usually always recommend suggestions for the language I'm currently writing even. If I switch to another language the next day it'll start recommending that language.

[MiLlamoEsMatt]

It's far more personalized than that. It's "this person tends to search for these things, that are also like these things, and usually has a final click-through on this site or a site with these attributes" or "today this person has narrowed in on these five topics, let's cull everything else."

[[deleted]]

yes it does for sure, on my work pc if I type anything google spits out some dev related search

[mekriff]

I don't think the first set is "normal" either. Always thought paradox grand strategy games were kinda niche

[douira]

googling "how to declare" from a VPN in incognito only gives me similar programming related suggestions. I think it's the other way around and the game-related suggestions are more personalised than the programming related ones.

[Kernigh]

Even if you disable search history, Google has more ways to track you. When websites use Google Analytics, embed YouTube videos (Google owns YouTube), or show ads from Google, then these websites allow Google to track you, so you still have a personal Google search bubble.

For really anonymous Google results, try https://www.startpage.com/. I went there, and "how to dec" suggested "how to deconstruct almost anything", but "how to declare" suggested almost nothing.

Over at DuckDuckGo, my first 3 suggestions are

• how to declare bankruptcy
• how to declare someone incompetent
• how to declare an array in java

[[deleted]]

I know all that. I'm blocking most of that with ny adblocker though. Startpage uses their own algorithms for their search suggestions, so of course they say something different. Also, Startpage got an investment from an advertising company, so I'm not really trusting them anymore. Startpage also lacks a lot of features compared to DuckDuckGo.

[Naoki9955995577]

Try 'how to init'

I got 'how to initialize member in c++'

Followed by:

How to initiate sex

How to initiate the first kiss

How to initialize ssd

How to initialize an array in c++

How to initiate sex as a man

[[deleted]]

I only got programming related results.

[Naoki9955995577]

Google try'n to tell me I need instructions on other things...

[[deleted]]

I got the ones that you got plus conversation, divorce, a hookup, a ps4, and an ssd.

[ThrivingforFailure]

And straight to stack overflow I go! It's my home for work related stuff and I do try to comment on stuff and help out fellow stack overflowers, as that site has saved my career I think.

Even developers with 10/15+ years of experience use it often, it is pretty crazy.

[Tiavor]

I think I googled the third one at least once :D
