It doesn't matter what they told you, because this is not their site. Questions asked here must be in compliance with this site's guidelines, and the guidelines here are exactly as I explained before. Contact LinkedIn Customer Service for questions that are not specifically about programming (code) related to their API. The only questions that may be asked here are about programming (code) or use of programmers tools. We cannot speak on behalf of off-site, third party vendors, their services, licensing, or issues specific to your account. — Ken White 44 secs ago

I'm thinking we'll need a minimal reproducible example to give you a 100% correct answer that's useful to other programmers in the future. — user4581301 1 min ago

Welcome to Stack Overflow. Please read Open Letter to Students with Homework Problems. You can't just dump your problem statement here and expect us to do it for you. It's also a good idea to take the tour, read about what's on-topic in the help center, and How to Ask. — Chris 27 secs ago

You asked this question before and were told that this site is for specific questions related to programming (code) or use of programmers tools, and that is was not a site for polling or collecting lists. There is still not a specific question related to programming in the post. — Ken White 55 secs ago

It's not a programming question. It's not about what is supported by current processors or OSes. It's asking for speculation about what might be possible now and in the future. It's not a specific question related to programming (code) or use of a programmers tool. It does not fit within the current site guidelines in What topics can I ask about here?, but more in What questions should I avoid asking?.as far as being primarily opinion-based and asking for discussion. — Ken White 50 secs ago

@Software Engineer <%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %> is an import that you add to the top of the jsp file. — Dot Batch 48 secs ago

When I look at my code in my head -- Use the debugger that comes with your compiler. Programmers do not just rely on the code "in their head". They use the debugger to single-step through the execution of the code to see where the code diverges from what they have "in their head". — PaulMcKenzie 22 secs ago

There are some uses of volatile that are NOT deprecated, because they are useful (e.g. in code that directly loads or stores from specified memory locations, such as in device drivers). Quite a few of the "deprecated uses" are related to ability to use features that too many progammers use - incorrectly - as a means of making a variable access atomic. The C++ library now (since C++11) provides a correct means of ensuring atomic access of variables, so it makes sense to discourage programmers from incorrectly using volatile when the intent is atomic access. — Peter 39 secs ago

I would like to highlight to viewers that this is actually a great question. Bit manipulation is not something that all programmers are strong with, and knowing the conventional hex/octal prefixes for integers is not exactly "fundamental" across the board. — CinchBlue 34 secs ago

As the creator and lead developer of the open-source documentation tool Doxygen, you might be interested in posting an answer to this new question: Free tools to assist code reading. — karel 36 secs ago

It's just an overwhelming question for me, I feel like I almost solved it, there is very little left, but I can't reach my goals because of a lack of experience! So I ask the help of more experienced programmers, that's all!) — Andrii Havrylyak 19 secs ago

@D.Nathanael Unfortunately we cannot make that assumption about pass by value and being copied because we don't know the specifics of underlying data structure. In some cases. You might be surprised to learn that passing by reference treats things differently than by pointer. For example, all the usual operators to the object apply, so it is in fact possible to make a copy of the object in his example even though it is passed by reference. This is a major distinction programmers need to realize. — Paul Renton 12 secs ago

I'm voting to close this question because questions about the software development process and software engineering, including quality assurance, architecture & design are off topic on Stack Overflow. You might try posting on SoftwareEngineering.SE. — Dharman 53 secs ago

We're programmers, not psychics. We cannot read your mind and see your code. You have to actually show it to us by posting it in your question. — MarsAtomic 42 secs ago
