@talex however I rely on this website to ask questions since there are experienced programmers who know the expertise of this very well — TechGeek49 just now

This is a bit of a complicated question for stackoverflow; I recommend Software Engineering instead. At a glance, the best solution would appear to be to use a database of some sort, one that supports versioning (depending on your data, a NoSql database might work better than a Sql one), and tag each insert with the appropriate version. — Green Cloak Guy 8 secs ago

Also notably, if you have a heap present in your Cortex M0 application, you are using some sort of PC programmer quack project. It would need to be saved from the PC programmers, which is usually a whole lot of work - usually you'd just toss it in the garbage and rewrite it from scratch. — Lundin 28 secs ago

@sahn Well your question is really leaving a lot out. Like, the reason things are arranged like that and what you actually want to end up doing. Designing APIs might even be a better question for Software Engineering. — Zan Lynx 1 min ago

I’m voting to close this question because it is not related to programming. Try pm.stackexchange.com or softwareengineering.stackexchange.com — Vadim Kotov 31 secs ago

@DanAbramov I appreciate your effort to make the post, without it I probably wouldn't have been steared towards react-dnd so quickly. Like many of your products, it seems needlessly complicated at first, but put together in a primely professional manner (going through your documentation I usually learn a thing or two about software engineering...) I've read "those who don't know unix are doomed to reimplement it... poorly," and I feel something similar may hold true for many of your creations (including this one). — Nathan Chappell 28 secs ago

Welcome to SO. Please read What topics can I ask about and How to ask a good question and The perfect question. SO is not the place to ask for a tutorial, nor the place to find free programmers. Your question should show that you've put some efford into solving your own problem and should be answerable without writing half a book. — icecub 24 secs ago

@KadirDokur The point is rather that SO was never meant to an interactive beginner tutorial nor a replacement for studies, but rather a place for professional & enthusiast programmers. Yeah, it is OK to ask beginner-level questions here, but a bare minimum knowledge of the topic might be assumed. In this case, casting a glance at the mentioned chapter of functions in the C beginner-level book might reveal the answer, in a way that is more pedagogic and easy to understand than any haphazard answer posted here. — Lundin 15 secs ago

@klutt There are many answers of .low-qualified programmers that are upvoted. Passing by reference - is a general mechanism of accessing directly objects instead of copies of their values. And such a mechanism can be implemented differently in different languages using their own terms. — Vlad from Moscow 6 secs ago

I think this is a good question to ask over at softwareengineering.meta.stackexchange.com. This forum is for very specific code questions. Tha one is for overall theory or architect questions. — Casey Crookston 59 secs ago

@ryyker It is in C++ passing by reference is simulated using pointers. Passing by reference is a general mechanism to provide a direct access to an object. And in different languages this mechanism is implemented differently. Even in C++, C# and Java this mechanism is implemented differently. The common mistake of programmers like you is that you take terms from other languages and try to apply to another languages that have its own terms. — Vlad from Moscow 56 secs ago

The common mistake of programmers like you is that you take terms from other languages. I do not think I am borrowing anything from other languages, and I think I am in good company with saying that C does not pass-by-reference. In this answer you are taking a very non-idiomatic view on this point. — ryyker 11 secs ago

As of Spring 4.3, you no longer need the @Autowired annotation to inject beans. Constructor injection is now the preferred method. See link — Pastafarian 14 secs ago

Thanks for clarifying here, but could you edit your answer and add the explanation there? High quality answers improve the SO for all programmers looking for answers, plus there may be more upvotes in your future when your answers are clear. — tshimkus 31 secs ago

Okay - I concede that & would be just as bad as |. But the argument, that some OS has command line shells with a similar symbol is a weak argument, IMHO, because C++ programmers come from all walks of life. And either there is or there will be next year or the year after some programming language or environment which uses | as a comment... But for C/C++ people, & and | already have a fixed meaning. Also, I think this feature should come with compiler support (loop folding) and as such, it could get its own new syntax. — BitTickler 17 secs ago

Asking for recommendations for software is off topic for Stack Overflow (that's what softwarerecs.stackexchange.com is for) — hardillb 51 secs ago

Dude, I can read the docs. I'm asking you to explain your method and why. My example is not actual code I write, it's pseudo-code to get answers from other programmers. — billy_comic 35 secs ago

"I have a task", please elaborate, I only see an equation (and that already assumes it is not an assignment, keep in mind we are programmers here). Please clarify what you mean by ^ we programmers see a XOR there, but you might mean exponentiation. — Yunnosch 5 secs ago

I would recommend using Double.parseDouble(input.nextLine()); instead of input.nextDouble();. Scanner has some behaviors that often catch new programmers unawares due to the way it clears it's buffer. I recommend reading up on some of the various help out there regarding this behavior. — Tim Hunter 1 min ago

You can't simply copy and paste your homework assignment here and expect someone else to do it for you. Please see: Open letter to students with homework assignments. — EJoshuaS - Reinstate Monica 12 secs ago

Questions asking us to recommend or find a book, tool, software library, tutorial or other off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it. You may be able to get help on the Software Recommendations Stack Exchange. — MattDMo 39 secs ago
