Where's my prize
C++class A {
private:
int x;
public:
int thing() const;
};
that const just means the function doesn't change x, right? I keep using it like that's what it does but I'm not sure.
>>51731525
yes.
>>51731525
shouldn't the const go before int?
yes, all it does is make it immutable
>>51731609
noice, ty
>>51731612
that would make thing return a const int
>>51731612
a const always applies to whatever is left of it (except when it's the first keyword, then it applies to whats right of it)
in this case, the function itself is const, not the return type.
Is it worth writing object oriented C by pretending C structs support functions using function pointers?

Particle simulator.
>>51732010
In the .webm I posted, a line segment is made for every animation step, so each particle has like 5000+ lines attributed to it. Plus paths are drawn until a particle dies.
I've changed it so lines are made for every 10 steps of the animation (so instead of 5000 line records, only 500). The path is aliased but still smooth enough and doesn't kill performance.
So I was reviewing my code, and the one thing that I get wrong is that smallest gets reported right, but largest gets me a huge negative number instead of the lowest number that I inputed. Is there a way to fix this?

FUMBBL has everything from the tabletop game and official rules, super friendly and tight community, spectator sounds (all games with spectator modes should have this, so good) and is 100% free, but has super shitty graphics, is less friendly to beginners due to giving you less information and the community is smaller
the videogame has better graphics, has a bigger community, is more friendly to beginners but it's incomplete in terms of teams and rules, some stuff is buggy, the community is flakier, it's not free, has some dumb rule changes, no spectator sounds!! and Cyanide

This just shows how disconnected from reality you are, if anyone ever dared to commit code like this in a mission-critical project he'd be fired.

What's the fastest way to "convert" a 128 bits integer to 16 bits ?
By convert, I mean setting a bit in a 16 bits integer if a byte in the 128 bits integer is non-null.
>>51734580
Also, consider you can only access the 128 bits through 4 32 bits ints.
>>51734580
In what language? A 128 bit number is 16 bit is you interpret it as 16 bits. just ignore everything after the first 2 bytes.
I asked yesterday, but got no replies, so I tried to find the answer through google, but no avail.

It's a simple quiz game with 4 choices where I want to highlight the correct answer when someone gets the answer wrong. The point is to get kids to learn the word, not to penalize. However, I have no idea how to highlight the correct answer. I thought it was the "elseif btnoption1,2,3,4.text.equals.correct1" parts I put under each button, but that doesn't work. It takes the vocabulary from a text file, as well as the correct and incorrect words. Does anyone know how to highlight the correct word when someone clicks the wrong one?
Yes, it's Windows, yes, it's Visual Basic. Insult me as much as you guys want, I don't mind. But if anyone can just point me in the right direction, I'd appreciate it, thanks.

This looks pretty bad, and for the most part not simply because you're using VB (although you really should be using C#).If btnOption4.Text.Equals(key) Then
Incorrect = Incorrect + 1
allpoints = allpoints + 2
btnOption4.BackColor = Color.Red
ElseIf btnOption2.Text.Equals(correct1) Then
btnOption2.BackColor = Color.Green
ElseIf btnOption3.Text.Equals(correct1) Then
btnOption3.BackColor = Color.Green
ElseIf btnOption1.Text.Equals(correct1) Then
btnOption1.BackColor = Color.Green
End If
There are 4 blocks of code here, and because they all are inside if/elseif/endif, at most one of them is going to happen. What you want, as far as I can see, it for two of them to happen.
So, in pseudocode, rewrite your code to be this:if(btn4 is incorrect){
incorrect = incorrect + 1;
}
if(btn1 is correct){
btn1.color = green;
} else if(btn2 is correct){
btn2.color = green;
} else if(btn3 is correct){
btn3.color = green;
} else{
MessageBox("There was no correct answer, sucker!");

The algorithmic language Valutron.
Valutron is my algorithmic language for programming computers. Derived principally from Scheme (as defined in R6RS) and from ISO Lisp it provides an object-oriented and functional environment in which to build software.
The two main features Valutron offers that define it apart from other languages are, first, a powerful object model descended from iLOS (ISO Lisp Object System) and that of Objective-SmallTalk, which permits extreme dynamism and uses total-late-bound multimethods; the second, a code representation called V-expressions, which provide an algebraic syntax option for the language.
The implementation I am working on is called Valutron QuickSilver Performance Engine. It is written in Objective-C. Input is first transformed into Cons trees and then compiled into bytecode, which is executed in a precision virtual machine whose design incorporates influence from Gnu Guile and the SECD Machine. A clean Trace-and-Sweep garbage collector is used to manage memory use; this collector is very efficient and fast, and leaves little reason for anyone to prefer manual management.
Finally, Valutron offers a pleasant interactive REPL environment.

Is C# MVC a good place to start moving away from php?
>>51735338
How is that any funny? 30 years ago most started with C.
>>51735338
I honestly think that either extreme is good, no in between stuff, either go highest level or lowest level within reason of practicality.
With something like Python you can still learn concepts just fine without knowing all the details then learn more later if you want/have to, starting on the other end with C you'll learn a lot from it which translates to other languages being easier to pick up or work with later as well as some insight which may be useful even in other languages.
>>51735363
C# seems very convenient to write code in. Especially latest versions. There is honestly nothing in it that Java can't do, but C# just offers a much easier path to achieve your task.
>>51735375
30 years ago everything was CLI garbage.
Java is a fine choice, good salaries, easy to work, shit ton of documentation and libraries.
better than C for most shit, unless you wanna do drivers and kernels.

>How is that any funny? 30 years ago most started with C.
nope, c never been popular in academics (take looks at the papers of the time if you doubt). pascal, simula, lisp, fortran, ... those were popular.
>>51735410
Yes, why? I've succeeded using different methods for different people. There is no perfect answer for everyone and everyone learns differently, some people react better to lectures while other react better to books on their own, some people prefer to dive in while others would rather start slow and shallow.
What I'm saying is what worked for you will not work for everyone and what worked for me won't either, no one approach is inherently good or bad it's very personal and specific.

>>51735363
C# is a very good choice because it's easy to then switch to Java if you need to (almost identical syntax, different framework), and it's good for learning other C-like languages (namely C, C++, and D).
You also end up learning the .NET framework, which lots of languages like VB.NET, F#, and IronPython use.
You can also use C# as a direct replacement for PHP by means of ASP.NET.
>>51735249
what happend to the github repository ?
>>51735448
In between is a mess, if you're going to start you should start at one end or the other not in the middle. I'd say lisp in itself is on par with C in terms of a starting point although it's certainly a different path.
What in particular do you have against Python?
>>51735429
Using their creativity to think of something they want to build and help them pick out a language. It might not be the best language they choose, but it's important that beginners have fun and are not bound to a language because it's a very good language to understand concepts with.

>>51735494
>What in particular do you have against Python?
i'm not going to bother with this shit for the nth time
but basically python hides as much as possible from you, no explicit types when declaring variables, doesn't teach that you're doing very simple operations on sets of binary bits. it's a bunch of "magic" that you don't know how it works. at least C is much better in that regard but you should pick a solid middle ground instead. you fucking murricans have no concept of "lagom"
>>51735061
Thank you for your previous suggestion, but changing it did not work. Yeah, I should have clarified; correct1 is a textfile with all the correct choices, and incorrect1 is a textfile with all the incorrect choices, it's declared at the top. Do you want me to upload the text files? Would that help?
>>51735511
>Putting people on the hardest shortest path to picking up a new skill never worked with anyone I worked with.
It's the minority for me for sure, to reiterate there is no "cure all" when it comes to teaching. In my experience the hard path is not the short one either, learning C certainly takes longer for a beginner as there's much more to cover which for some people is actually counter productive since it's information overload on all these new concepts. It's certainly not the right approach for everyone but it can be for some, obviously if people benefit from this then they should go that route, if they're struggling too much it's the wrong way to go about it but it should be obvious when you question them before you even begin down the path at all. It can be as simple as
>how do you normally learn things?
>would you rather dive in or tread lightly
>here's a basic overview of what you'd have to go over and learn, how do you feel about this
etc.
Take into account I'm no expert this is all anecdotal.
>>51735456
What's that supposed to mean? I worked to pay for my first computer and figured that shit out all by myself with a battered copy of K&R. If they're not interested by themselves, just accept them for the inferior breed they are.
>>51735600
Then the problem arises that a beginner wants to take shortcuts, trying to discover a 'secret' way. Overestimating how good they can learn and picking the fast route, which will bore them after a while.
>>51735519
Blind yourself.

>There is honestly nothing in it that Java can't do

>>51735551
You're not wrong, it's certainly magic but there can be value in learning higher level programming concepts first and the mechanical details of it later, for some people (this is key to what I'm saying).
I'm going to use a shit analogy here but it's like teaching someone how to mow a lawn, they just need to know how to work the thing not how it works, they can get the task done and then learn how the mower itself works and how to build one themselves later. I doubt that applies to what I said but I'm really fucking tired so bear with me.
>>51735640
I think that's highly personal, some people may have that problem but I don't think those that care will. I think that's why I have had such success, the people I am teaching want to learn these things for their own reasons, it's not like compulsory classes where people need to just get it over with. For more adept people the short path seems like a shortcut but to some it's not really a short path, they may struggle with it just as hard as others on the hard path, if anything the people starting shallow spend more time overall since they have to go over the same concepts again later. I hope that made sense, I'm doing a poor job right now which doesn't support what I'm saying. lol
You guys happen to know where I can find code for a java-based probability outcome simulator that takes a csv file and calculates based on an algorithm I already got? Normally I wouldn't ask for something so specific from here, but I'm at my wit's end.

If you were to write a specification for your own language, how would it look like? Is there any standard form that it should look like or should I just start throwing random descriptions about the specific features of the language?

First build the GUI, it doesn't have to do anything, just that it can start up
Second build that you load a file and print the contents in a console
Third build the algorithm in the program and print the results in the console
Last make it display the results in the GUI.
Those steps should be pretty google-able.
I have a number of frames in a certain animation.
I want to instantiate a list and add a rectangle to each frame.
I want to use a foor loop.
should I use:
for (int id = 0; id < animation.size(); id++)
or
for (int id = 0; id = animation.size(); id++)
Which one?
>>51735947
2nd one
>>51735399
>>51735477
Thanks
>>51735947
I know nothing about animation but I would think the first one.
>>51735947
The second one will assign animation.size() to id on the first iteration, are you sure that's what you want? Also you probably want to get the size before the loop.

>>51735947
What's wrong with "<="
>>51735998
When your animation has 8 frames it'll do 0 1 2 3 4 5 6 7 8, resulting in looping over 9 frames instead of 8.
>>51736021
so, should I use < instead?
>>51736034
I don't think it would be a good idea to try to loop over 9 frames when you only have 8.
Try it though, you'll see it'll give an out of bounds exception
>>51735947
You should also consider assigning the size() to a variable before the loop. For all you know, it may be re-computed on each call.
>>51735989
Thank you!
>>51735947
I would also try using this instead, unless you have to use id for something.//Replace Object with whatever class you use
for (Object frame : animation) {
//Do something with frame
}
>>51736070
dunno, < gives me the number of frames I want.

Almost every language can accomplish the same tasks in that sense.
>>51736295
Well, for example, in Pascal you can't create a library that would accept a string of a vriable length, in C and C++ you can't have inspect/debug your program reliably after something goes wrong, in Javascript, you can't do file i/o without third part extensions...
>>124551909
nice
>>51736322
but you can still solve the same problem with all those languages.
Java methods can't return unsigned integers, accept pointers or invoke native code easily.
>in Javascript, you can't do file i/o without third part extensions...
io libraries have nothing to do with the core language.
>>51731376
Terrible. This is far more idiomatic;
char *
xorblock(char *dest, const char *src, size_t len) {
for (size_t i = 0; i < len; ++i)
*dest++ ^= *src++;
}

How do I run something like this without passing var?

The function has 4 different options and one of them I'm trying to add needs the variable.
But it breaks all the other ones because no variable...
>>51736586
If one of them is not optional you must pass that argument. If you just don't know how to do optional parameters in Python, then Google that.
