That's something that the malloc implementation does.

>>59057667
>total size of heap is what OS does for you
Normally (on Unix-likes), brk/sbrk needs to be called so that the OS will resize the heap, but that's something the malloc implementation will do.

>>59057672
Practice. Recursive programming isn't hard. The hard part is spotting the right situations to use it.

>>59057726
there's almost no valid situations where recursion would be useful unless you're using trees, and those have very limited use cases where they wouldn't degenerate into a straight linked list.

>>59057735
>very limited use cases
What?
Trees are useful as fuck, and are used all over the place.

See >>59057811

>>59057873
I went on exchange to MIT during my university days. That was prior to them switching to python. I don't understand why they would switch it but most of the people there are already smart enough that it doesn't matter if it is coded in Python or Rust or even in Assembly. One of the few places I have been to that made me feel stupid but I did love America a lot.

>>59057872
The same reason other places hire them. Because they do it so much cheaper than a local would that the decline in quality is deemed acceptable.

>>59057904
That feature is necessary for C toddler refugees so that they can learn how to write programs.

It's literally nurturing a C infant

>>59057922
So you're saying you'd be able to program safe programs without the borrow checker? Why not just use C then?

>>59057951
Because C has fuckton of undefined behaviors

>>59057959
>undefined
You mean platform dependent?

>>59057980
UB allows the compiler to generate a lot more efficient code.
UB allows the language to be much easier to implement.
UB allows the language to not have to define ridiculous situations where there is no reasonable answer.

The thing which is actually a pain in the ass is implementation-defined behaviour.

Bout to make my first issue in an open source problem

>>59058006
If you are depending on UB to generate "efficient code" you really need to rethink your algorithm

>>59057225
By installing gentoo

This is stupid of me but how do I use two inputs as arguments for a function call without setting up variables?

def weekDay(x, y):
    return days[(x + y) % len(days)]

weekDay(int(input("Input number of days"), int(input("Input starting day"))))

>>59058025
It has nothing to do with my algorithms. It's to do with the compiler.
A compiler is allowed to assume that UB can never happen, and is allowed to optimise based on that assumption.
So it can take statements like (x < x + 1), and just replace that with (true), as it can assume that signed integer overflow can never happen.

Anyone, the original discussion before the Rust user derailed it was that Rust users aren't actually smarter for having the borrow checker do the thinking for them

>>59058050
jesus fuck you're too stupid for this

That is something else.
>If you are looking to improve your efficiency, optimize your model
How is forcing the compiler to add more checks going to make the program more efficient?
Some languages might be able to add more to the type system to try and remedy that, but Rust certainly isn't the shining example of a type system that is going to generate efficient code.

>>59058181
it uses way more memory if you do that

>>59058199
You are not at the stage where you need to worry about memory yet.

But to answer your question, create another function to store the inputs and then use that function to pass the inputs to your other function.

Yet people still use C today, probably because it's the best language for the job it was intended for: near bare-metal interaction and OS development. Rust doesn't have the same niche nor the same necessity in today's world that C did in the early to mid 70's, when it was being created for UNIX. Why should you use Rust today vs. C? C has all the important features Rust has and is less inhibited by security,making it faste in addition to being more portable than Rust. Even in the 70s, this was the same basic reason C won out over less memey languages like LISP, Pascal and FORTRAN (although even they still ahve their uses). Rust honestly doesn't have a niche like C does since it's not as fast as C and not as portable as C, which was the entire fucking point of making C in the first place. If you want to sacrifice those things, sure go ahead. But the majority of programmers think thoe benchmarks are important so don't go around acting like Rust is some godsend when it's really just a piece of shit.

Responses from that thread:
>For most uses there's not a huge difference in timing between C and C++, but for the simulation work I tend to do I need to squeeze every available bit of performance out as possible (time-domain simulations are a bitch) so using C is really the only way to go. Plus it's slightly easier to call from my Python graphing interfaces (using ctypes) due to C++ name-mangling - obviously you only need to add some "extern"s in c++, but why bother when you can use C which is faster for these simulations anyway.

>Learn the language you're using from inside out. Don't rely on copy pasting stack overflow and cry a river when shit goes bad. The language was created and is good. If you know how to use it correctly, nothing bad will happen. So yes, it's the coder's fault.

It's like being a good programmer requires you to know the ins and outs of your language by reading the documentation and everything is essentially the fault of the programmer. Like that C is very important when it comes to bare-metal interactions or speed. Really makes you think...

1. Java never was going to replace C, C++ was. C++ has replaced C, making C limited to embedded systems programming these days.

If you look at large open source C projects or if you have worked on closed source C projects you will notice the developers are dying to write C with Object Orientation mockups in the most pathetic matter.

>Rust honestly doesn't have a niche like C does since it's not as fast as C
I hear this a lot of times. but C doesn't have any concept of concurrency like modern languages, less memory is irrelevant in the age of multiple processors and threaded programming. The efficiency of hardware has increased while C is stuck in the 80's model of computing.

>C has all the important features Rust has
You don't want to go there, my child

> Rust is some godsend
It's not. However it's a major improvement on C++, which was a major improvement on C.

>more portable than Rust
Another buzzword. The RustC uses LLVM backend, any architecture LLVM works with, Rust will work (if not it already does)

>Rust doesn't have the same niche nor the same necessity in today's world
It does, safety is a major requirement now that security is a major consideration. "Safe C" courses and guidelines is a thing, which Rust deprecates.

You are just upset that C is being shat on while you C toddlers do the same with python and JS fags. How ironic that you can't handle simple banter.

>C++ has replaced C
Yet why is C still almost an industry standard when it comes to making drivers and low-level software where performance matters (along with assembly of various archetectures)?

>it's a major improvement on C++, which was a major improvement on C
More features != an improvement. C++ wasn't really an improvement on C. C++ is slower than C in terms of performace (you know, the whole purpose of making C in the first place) and even that is eons ahead of Rust. So yeah, people that are concerned with performance use C probably.

> The RustC uses LLVM backend
Great. C runs on bare metal. Guess which one is faster?

> safety is a major requirement now that security is a major consideration
No good coding practices are what's needed, not more security features which slows down the language. ALL performance critical code has to use a memory unsafe language. I mean, you can't have your pie and eat it too.

>You are just upset that C is being shat on while you C toddlers do the same with python and JS fags.
No. I'm not mad. i just think you're a stupid webdev that can't read the fucking manual, has bad programming practices if C fucks up n you constantly and doesn't understand the concept of using different languages for different puposes. I wouldn't use C for something Haskell or LISP is more prepared to do or vice versa. Likewise, I wouldn't use Rust for anything C is supposed to do just because of C is honestly more adept at what it does than Rust will ever be.

I don't know, I've always used Community edition. Make sure to google how to set line numbers (they might be enabled by default now, been a while), and I really like dark mode + monokai style.

Once you begin writing your code, under 'Run', you can select 'Debug <program name>. Set breakpoints by double-clicking neat the line of code you want the debugger to stop at. A small window will be open showing you allocated variables and their values (inc. maps, lists, ect). F7 then allows you to "increment" the program by a line at a time (there are other ways to move the program forward as well, see @ top of the bar in 'console' window).

>>59059321
I don't know if I would do it the way you have. Grab the current lowest 4 bits with something like:

val = num & x0F;

Then depending on the integer value in val is <= 9, take val + '0' (otherwise (val % 10) + 'A' or something) and put them into the char array in reverse. Then right shift num 4 spaces over: num = num >> 4;

And loop. This would work for 32 bits, 64 bits, ect.

Is anyone else unable to create new threads because file uploads keep failing?

You call the method that prints something in class B from class A. Like

public class A {

        otherClass.print();

}

Christians are literally the worst out of all Abrahamic religions .. cherry picking hypocrites.

It's honestly quite pathetic.

>>59060438
Those are actually muslims. Not only do they cherry pick, they cherry pick to the fucking extremes.

guys can we pls stop arguing about religion and discuss what brand of panties is best?

>>59060449
fuck panties; leggings a best!

>>59060438
At least christians follow some of the new testament. Jews completely ignore the entire torah, except for "give reparations".

>>59060438
>Christians are literally the worst out of all Abrahamic religions
you can only say this if you literally haven't heard of Islam. either that or you're simply delusional, even more than the people you seem to hate.

>>59060448
the whole christian religion is based on selected verses from the old testament, chief.

>Christians believe the old testament is the word of God
>But this version of God's word is better!
fucking brainlet christians ..

Yes but they don't murder people over it in current year so that automatically makes them not the worst.

How would you randomly retrieve all items from an array? Would having all the indexes in a link list then doing a rand(linklist.length) be good? Popping it off each time?
