Can you guys just sit and code straight without being interrupted by having to research or look stuff up? I have to stop and do research,r look up documentation, or look up examples from other people's code all the time is this normal or am I a brainlet?

>>61308761
That just means you're not coding fizzbuzz tier shit.

>no one will ever create such a perfect game again
Man desu minecraft reminds me of Cataclysm DDA: a game that was initially perfect but eventually turned to shit because so much bloat was added.

Haven't played it in years but looks like the game got bogged down by a billion new features.

I originally did the nehe tutorials, but I can't recommend them as they're for antique opengl 1.1, which is incompatible with current opengl. I read the opengl superbible to learn 4.5.

My game is being designed with modding in mind. The backend is in C but high level code is in scheme. The goal is you can distribute mods as compiled shared libraries that the game loads from a mod folder.

Don't use braces for single-line conditionals and loops.
You could even do something like this and it would only require one semicolon

Couple of things:

>Better variable names than 'array'
You look like you're doing this pretty well with names like "fileHandle" and "filePath", but with variable names like "char1" and "char2", it's not too clear what they mean.

>Decomposition
If you have a large block of code, it's usually better off being delegated to a function.

>Comments
This should honestly go without saying, but a good way to see if your code is well-written is to ask yourself "Can someone with know knowledge about what I'm doing understand this?"

You also get better at writing code with experience

>>61309893
use whitespace/comments between code chunks

Anyone Prolog here?
I'm playing with PLCs and their programs are written in ladder logic, and I was thinking of writing something that could do some automated testing for me. Like, "given all these boolean logic statements, will these two outputs ever be true at the same time? No, cool."
Would Prolog actually work for this or is there some better choice?

Don't need to. That's enough to make it not deprecated.

But here's another feature that makes C not deprecated: no retarded name mangling, so it's good for libraries.

>>61310062
It's essentially language agnostic, equally accessible from assembly, C, C++ and probably many other languages. And I don't think there is much pure C left in the current implementations of windows - and regardless, using a language with classes is useful when designing any kind of non-trivial application. Just because you can interface with the API from C doesn't mean you need to limit yourself to C.

Not a replacement since C was created in response to the deficiencies of assembly.

I remember Mike Acton in "Data-Oriented Design and C++" casually mentioning that they would've liked using assembly fulltime. Was he being ironic or are or were console gamedevs really that concerned with performance?

>>61310217
there might be a cleaner way to do the array where you won't end up so nested, but you'll have a lot more lines and have to kick some of that stuff to functions.

>>61310246

You can solve the same thing in scheme very easily with amb. So I can't really think of a good reason to use prolog myself.

It would marginally improve your code's modularity if you'd try to avoid magic numbers. If you're concerned about the overhead of runtime constants, you could always use macros, but if you have to use a number more than once, anything would be better than just the bare number.

Running through a WebKit app is so cringe. Even as a JS developer I'd rather communicate with the backend via native code.

>>61311474
Yeah, I can see a few of those. I should put the """"""JSON""""""" writing in a separate function too, right?

>>61311524
fuck off, macros are disgusting as hell, and C is fucking garbage for not having constexpr

Reminder that C and C++ do in fact have modules. They're called compilation units. Headers exist as an extension of this facility, not in its stead.

>>61311573
No, you fuck off. Macros are elegant and necessary. Constexpr is garbage. Only functions should be inline, if a variable is inline it's not a variable it's a macro.

> why?
I suppose it's a personal touch, But I don't think WebKit apps are as stable as communicating directly with the OS API.
It's like having a layer on top of another layer of code just for the sakes of simplicity.
Don't get me wrong, if you're making a basic app ( like a click and go type thing) then you're ok, but for advanced and ""resource"" heavy apps ( real-time node to node ) it's just not beneficial user end.

You're waifu a shit

>>61311380
26 is more than 2, so if you create 26 piles you have created 2 piles

>>61311703
26 != 2

What's the compiler keyword for a function that never touches the state in C? Takes input, does something with it, returns output.

>>61311725
__attribute__((const))

>>61308604
ncurses shit

>>61311725
__attribute__(((const)))

>>61311737
but those aren't standard, are they? (genuine question)

>>61311722
there's no way to reliably create exactly 2 stacks in that problem which solves it so it's obviously not asking for exactly 2

>>61311745
no it's a compiler extension. C++ has constexpr tho

>>61311745
No, it's GNU C which means it's available in GCC, probably in TCC and maybe in Clang.

>>61311745

Yeah, if your idea of free is handcuffing yourself to prevent yourself from stealing shit, even though you have no history of theft.

>>61311777
the cards are randomly distributed throughout the deck, so as i said that isn't a reliable solution

I can agree with that much. Trying to wrangle a large database and keep it synced with a central server is not super fun. I have yet to stick my nose into React, which according to supposedly in-the-know people is *the* way to handle UI efficiently.

>>61311777
How do you know which 13 if you're blindfolded?
Making piles of 2 (or 4) cards each is the only way to divide the cards evenly and, with high confidence, guarantee there are at least two piles with the same number of face-up cards.

GNU is not free.

I had a phone interview a little ways back where the interviewer accused me of stealing the solution for the sample problem because he said it was too optimized for someone without a CS degree (mine's in engineering).

Is there a practical way to defend this accusation? I explained how the code worked but he still didn't end up buying it and I got passed on as a result.

The code was NOT complicated at all, it was just a python file that knew how to use list comprehension, dictionaries, and sorted().

The compiler is free as long as I don't modify it. The output of the compiler is free without restriction. Can you tell me why I should give a flying fuck about your ability to monetize it?

Is there any resources that teach C++ as an extension of C?
Like C++ with just the right amount of extensions like vectors, concatenations, tuples etc?

"open source software" technically cannot exist.

>>61311832
I've used react and it's overly complicated for what it needs to be. I've used Angular, which is more mainstream, but I personally use VueJS because it feels like a perfect blend of Jquery and Angular.
But regardless of the DOM framework, they will all sit on top of WebKit which is very resource heavy and mostly creates needles backend checks to the browser when you can create a native programmed app.

You've to remember that WebKit is designed for PC (both Windows and Unix based OS) rather than the low end 'smart' phones. And unfortunately, NodeJs is then only bridge between the two.

How can I use my .emacs file to make my life easier?

Specifically, I use an add-on, "sr-speedbar", and I always have to type

M-x sr-speedbar-open

And it just seems tedious... I'm pretty sure there's a really simple way I an avoid doing this by changing my .emacs file a bit... Is there?

>>61312040

this anon >>61311895 is under the assumption that there were always 13 face up cards in the deck.
the original problem >>61311207 however states that there's only 13 face up cards in the deck to start out with.
picking out random cards while blindfolded doesn't give you any information about the cards themselves.
you just have 13 cards.
are they face-up? face-down?
there's literally no way of knowing this.

Flipping a card doesn't guarantee a state, it only changes it.

Someone uses Emacs for Javascript? Atom and VS Code have a nice popup with annotation and a comment below.

I've spent some time fiddling with company-tern and company-quickhelp, but it doesn't come up together. All I get is annotation in the message window. I can't even get the fuzzy matching and it doesn't get any built in tern definitions, unlike the Atom which uses the same tern backend as far as I know.

Should I bother? I like Emacs but just really tired setting this all up.

>>61312122
Not even the other anon, but holy shit, are you serious? There are 39 face-down cards and 13 face-up cards in the original deck. Suppose you take 13. There are now two decks: one in which there are u face-up cards and 13 - u face-down cards and one in which there are 13 - u face-up cards and 26 + u face-up cards. Now, if you flip the 13 cards, you get 13 - u face-up cards on both.

>>61311207
While blindfolded cut each of the 52 cards into infinitely many pieces. Do not flip any of the cards or the pieces.

Glue the infinitely many pieces back into 52 cards randomly, again without any flipping.

Create two 26 card piles composed arbitrarily. Each will assuredly have 6.5 flipped up card incorporated into them.
