Got a new problem at the next task. It's to reverse a string, BUT the problem is, this task forces me to use [code}void wende(char String[])[/code] as function header.
That means I can't use the char* method to manipulate the string, right?

>>54927861
>It's to reverse a string
put the characters into a stack tbph lad
>>54927887
A buffer? That's what I plan. The problem is to get the manipulated buffer into the original string though. Since I need its adress for that.
>>54927887
>>54927904
nevermind, I can still use *String to get the adress of the original string

Web developer wanting to learn more about systems programming.
Recently had to use USB and an ANT (the wireless protocol) receiver to build some heart rate monitoring interactive display for an event. Thankfully there were JS libraries on NPM that handled reading from USB and all the wireless frame data, then gave me a relatively simple API to work with. I'd have really struggled to figure out the USB stuff myself.
From what I understand it couldn't be done purely in the node runtime, so it used bindings with libusb. That's the kind of shit I need to learn to work with directly I guess. So is it time to pick up the K&R C book, or should I approach systems programming from a more modern approach, like maybe Rust?
>>54927929
>>54927861
Here's my working solution. If anyone has suggestions on how to make it shorter and less messy, or more efficient, let me know.
>>54928089
give me a sec
>>54927636
Do you have any specific thing you're interested in in mind? Go is nice for networking and multithreading for instance.
>>54928089
why not just determine the string length, and then print it by character starting from the back and ending at 0? idk C so maybe that's a lot harder to do in C than i'm imagining since i'm a java pajeet
>>54928161
Because strings contain an unknown amount of '\0' characters at the end, and I don't want to print it.
If you were to just reverse all the content, you'd turnA B C D E \0 \0 \0 \0 \0 \0
to\0 \0 \0 \0 \0 \0 E D C B A
If you then were to print that, it would stop at the first \0, so right at the beginning.
What I need isE D C B A \0 \0 \0 \0 \0 \0
>>54928229
ah i see. do you need to have the same number of \0s as the original in the reversed one? because if not you could just advance the counter if it reads in \0 without concatenating it to a new string and then print the new string. but if you need the same number then you're right you can't do it that way
>>54927460
both are SHIT but out of those two options, definitely go
>>54928378
I think at least the char right after the end of the text has to be a \0. I think it's better if all the remaining ones are \0 though.
The array has a fixed size, so that means the fields have to be filled with something. Best is if the result is as the last line in >>54928229
>>54928229
You know how strlen works, right?
So I'm practicing functional programming, or rather, trying to program functionally (maybe I'm not doing it right?). I'd like some feedback;
1. Is this code functional in style?
2. Is there a better way to format the line returns and white space to make this more readable?
3. Is this a good solution?/*

no, strings have exactly one '\0', it's in the definition of the string

{
char buf[20] = "cuck\0";
printf("%s\n", buf);

}
>>54928795
This prints the reversed string to the console, right?
This works well, but I should have elaborated that the task is to modify the string to its reverse, not to print the reverse of the string.
so that str_rev(buf); causes buf to now contain the reverse of itself.str_rev(buf);
printf("%s, buf);
should then be able to print the reverse.

I think i have to, i dont want backup of it, but i want to have the original function still available for me.
My goal is to do stuff with the arguments before the function processes it. I plan to do this by:
- making a copy of the function
- modify the original function so it immediately jumps to somewhere where i do my thing with the function arguments
- then call the copied function to process the modified arguments
- and return, by doing this i return to the main process where the original function was called from
I hope thats clear.

I think you can do it shorter like this:void revert(char* c){

int x = 0;

for(--i; i>=0; --i) //note first --i
buffer[x++] = *(c+i);
buffer[x] = '\0';

>>54929250
Just save the address after your inserted jump to modded code and have your modded function return there.
Getting the 'size of a function' is not trivial (sometimes not even well defined, think a block with multiple ret instructions with branches jumping to different ones), you can try some heuristic searches for common prologue/epilogue code, but it's not foolproof since depending on which registers were used it will look different (especially if frame pointers are optimized away).

you can't simply do that; the function can have instructions with relative addressing (ie. it matters where the function actually is loaded and executed relative to the rest of the code in the module)
either use a pre-made api hooking/detouring/trampoline library or prepare to implement somewhat half of a disassembler on your own

Right after I swap 1st char of the string with the last one I'm losing its value for further iteration.

>make pi approximator through brute-forcing rand() numbers many times
>more instances often get it further away from pi instead of closer
Is this because the numbers C generates are not random enough? Or is this just how randomness works? one million attempts still only get 3.1 right.
I'm supposed to use the monthe-carlo-method, which is to generate random points in in a coordinate system between (0,0) and (1,1), then check whether they're inside of a unit circle centered at (0,0). The ratio between in-circle to in-square points is then pi/4.
Should I try a different seed every now and then to make it more random, or will that not make a difference?

rand % 1000 is not uniformly random.
See https://stackoverflow.com/questions/1340729/how-do-you-generate-a-random-double-uniformly-distributed-between-0-and-1-from-c
>>54930187
I think the issue is x = rand() % 1000. This does not give equal probability of producing every number between 0 and 9999. By the pigeon-hole principle, lower values of x are less likely, explaining why you're getting slightly larger values of pi than expected.
Consider switching to a language that has proper support for random number generation, like C++.

>>54930325
yes, %1000 was the mistake, because the highest result is 32768, which means that the first 768 possibilities of 1000 have a 1/32 higher chance to appear than the rest, if I'm correct.

You don't patch the original function back, what you do is save whatever bytes was overwritten by the insertion of the jump, and then just before you return to original function you execute those saved instructions (just like how you have to restore any registers or flags you potentially changed by your detour function)
Then you leave the added jump always in the original function.

Why? Does it still work? What's your result?

this but it should still work somewhat decently enough as long as his algorithm is correct

I laugh at all of the circlejerk mathematics that goes on in computer science.
"Q(p) is a function where q is the stability of the system, and p is a random variable we pulled out of our ass. As p increases, Q increases, but we don't have an actual mathematical relation; we just say it this way because fuck you."
Fuck everything about those impractical cunts.

Ho the baby OS. But my program is portable. It works on Windows too.
can arrays be implemented in a language that only has a 'define' and lambdas
y/no?

that was hard
I really wish I could focus on one programming topic without getting the sudden urge to start learning something else
I took two classes in Java at my school, and am now learning C for fun. Everything is weird.
Should I read pic related to bring me up to speed, or is there a better resource?
If it means anything, I don't consider myself a good programmer, nor am I wizard at Java.

God I hate that stupid algorithm to approximate π. It's not a good example for an algorithm to approximate pi, nor for integration, nor for monte carlo approaches.

Hey I have a problem I'm having trouble trying to solve.
I'm making a calculator in Python, but I want this calculator be able to support multiple operations and arguments.
So for example, someone calls it like this:
>Calc(5 * 3 * 1 + 5)
and it returns
>20
Now the problem I'm having is that unlike a normal function, I have no idea how many arguments will be passed. It could be 3, it could be 4, it could be 10. I have no idea. So I'm not sure how to define the function.
And even then, I'm not sure exactly how I would compute the arithmetic.
I'm a newfag at programming, so I'm not sure if this is over my head or not, but this is really throwing me off.
Any ideas? Maybe I'm just overlooking something. Could I somehow put all the arguments received from the function in a list? And then compute shit from it? I'd need to preserve the order of operations too.
>>54931307
read about variadic arguments/kwargs
>>54930665
oh ok
Thank you for your help!
So how are complex C programs (like le games) actually structured? They don't have objects so I don't really understand.
>>54931425
they use structs as objects and headers as interfaces
>>54931461
Where can I find an example?

How do i make sure i dont split an instruction when overwriting the original functions bytes?say i have this originally:
776A021E | 6A 1C | some instructions: push 1C
776A0220 | 68 00 BB 62 77 | some instructions: push ntdll.7762BB00
but i overwrite it with a jump to my function:
776A021E | E9 12 34 56 78 | jmp myfunction
776A0223 | 62 77 | some junk because of the overwrite

>>54931658
i give up
Well i hope the function im trying to patch have the right amount of instruction so i dont have to deal with that.
Maybe easier to check if there 5 bytes free before the function to do a long jump to my function, so i can do a short jump to the long jump in 2 bytes
jesus fuck
>>54931425
I usually just define structs instead of classes liketypedef struct {
/* ... */
} class_t;
and then associated methods asvoid class_method ( class_t *object, ... )
{
/* ... */
}
You should also implement a destuctor for convenience. It's getting pretty messy pretty quickly, so you should definitely sort things into different header files. Having at least some consistent naming scheme is also obligatory.
>>54931783
If you're gonna do that just use C++
>>54931822
A lot of people do that.
>>54931879
And most of them use C++
>>54931939
Not really, no. That's a common C technique.

personally I like Kochan - Programming in C
>>54931822
That is basically the absolute standard form for C programs that are just somewhat complex. You see that everywhere and I guess everybody who's programmed in C for a little while will end up with similar kind of structure.
>>54932090
You honestly should be programming in C++ because it has better syntax for this stuff
You're literally writing the C code C++ code could be directly translated to, plus C++ gives you scoping in terms of namespaces & member functions, and templating (which macros don't compare to)

Why reply to a non-argument with an argument? A non-argument suits a non-argument just fine.
>>54932172
Not an argument.

But what if the programmer doesn't want to use C++?

I have my reasons to use C instead of C++, so no thanks. Not everything ends up in that scheme I may have to add, of course there will be many methods that are not strictly associated with a single class. It's just how your code structure is usually organised in the end, if you want it or not.
>>54932237
What are those reasons?

C++ is a horrible language. It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it. Quite frankly, even if the choice of C were to do *nothing* but keep the C++ programmers out, that in itself would be a huge reason to use C.

You tokenize the string then apply operators and operands based on the token precedence and type.

Trying to teach myself Java and came across this odd exercise in my book:
>write a Java program that reads in a file and outputs the file as modified by the #include statements
So how do I go about implementing a preprocessor in Java? I'm not even really sure I even understand the exercise. I assume that I read an input file looking for #include and insert its content into the output file by using recursion?
>>54932969
really?
