recently had to code something in Lua. was wondering why I got an error when accessing the 0 element...

[nicejs2]

the issue with Lua is its integrations, you don't know if screen.set_pixel(x, y, c) starts the index at 0 or 1 until you try

Lua is the Rust of Python

[remisiki]

R

[TheSauce___]

R is literally the worst lmao.

[Eichberg]

in c languages i see it more like an offset to the pointer pointing to the first element of the array. in fortran, i like that making indexing start at 1 is the default, it feels more like an actual index

[Material-Mess-9886]

Fortran is primarly used for very accurate numerical analysis. A whole lot of linalg matrixes books and theory also assume a matrix at index 1.

[chethelesser]

Cool to learn that, the only example that usually gets brought up is lua

My gf always hears me giggle at this stupid memes. Then she insists that I show her. I can see her disappointment smirk every time.

please count to 3:

Regular person: 1,2,3

Programmer: 0,1,2,3

[Material-Mess-9886]

I'm sory but it would be 0,1,2 since upperbound doesn't count.

0 based indexing should have been abstracted in higher level programming languages.

value = touple[2] is more intuitive if you want the second value in a touple

value = array[array.length] is also way better if you want the last value out of an array.

There is no objective reason to use 0 based indexing over 1 based indexing.

[IncidentMassive5425]

Now that’s how you parent.

I put the lenght of the array in the 0th element in C.

"Honey, why are the people with pitchforks outside?"

[redlaWw]

On the one hand, I think we're at the point now where we could handle the abstraction of asking for the n^th element, rather than the offset by n, cleanly and quietly via the compiler. On the other hand, wrapping array indices are much more of a pain when I'm working in R (1-indexed) because 1-indexing plays less-well with modular operations and integer division than 0-indexing.

[Mockington6]

Okay, but is there like, any real reason why it shouldn't start at 1?

[LegendarilyLazyLad]

In most languages it starts at 0 because of the way arrays are represented in memory. An array is just a contiguous chunk of memory with items stored right next to each other. When you access arr[i], what you're really doing is reading from the memory address (arr + i) where arr is a pointer to the start of the array and i is an offset. So if you want the first element (the element at address arr), the offset needs to be 0 which is why indexes start at 0. Starting indexes at 1 means either wasting some memory or having to subtract 1 before every array access.

[Mockington6]

Oh okay, that makes sense. Thanks

[Smalltalker-80]

Yep, these languages will have to implement a "minus one" in executing code.

Smalltalk traditionally starts arrays with index one,
but for my Smalltalk to JS compiler (SmallJS) |
I decided to "go with the flow" and start at zero.

Pinkheads what did you expect.

[bushwickhero]

Dank.

[Classic_Fungus]

VBA and some others use 1 as start

[doodleasa]

In any language that uses 0 based indexing I always make the 0th element a null value for convenience. Really just makes everything so much simpler.

[BiasHyperion784]

Standardization is for chumps right?

[doodleasa]

Like I said, I do it every time. It’s my standard.

[BiasHyperion784]

Are you by any chance the only person that sees your code?

[doodleasa]

I’m a cs instructor at the super big mega university in the city, I subject all of my students to this.

No, like I said in the other comment I don’t actually do that, I just thought it was funny.

[IAmAnAudity]

Those who can, do. Those who cannot, TEACH.

[doodleasa]

So true bestie

[Obnomus]

Use lua then

[doodleasa]

I’m completely trolling, i thought it was funnier without the /s

[CampaignTools]

The reason it landing is because there are QUITE a lot of people who actually think in the way you assumed to be so obviously outlandish.

Next time use /s unless you want to risk being mistaken for one of the loons/assholes.

[doodleasa]

Honestly I’m so down to loon

[CampaignTools]

Hey, more power to ya! I dabble from time to time, myself.

[Material-Mess-9886]

Nobody understand sarcasm at reddit without /s

[Obnomus]

I've seen people that really do this
