Any ideas where to start learning C++ as an embedded developer? I wrote many lines of bare metal C code and want to transit to higher level jobs. I see many expensive or completely free courses, but I am not sure which one is usable in my complicated situation.

> You should almost always be using unique_ptr or shared_ptr I really wish there was a thread unsafe version of shared pointers, without atomics overhead, in the standard. Maybe without weak pointers.
If there's one thing C++ needs, it's more slightly-different varieties of smart pointers in the standard. ;-) What exactly would you use these for? I find that usually I can get away with unique_ptr for the sort of object that I have many of where pointer performance matters.
looks good,is there one pdf for all chapters?
I have cloned the repository then combined the chapters using pdftk: pdftk *.pdf cat output Modern_Cpp_Programming.pdf
I've been setting up my little docker image that has both llvm/clang/tidy/clangd and gcc inside with boost with an idea I'd run it and from outside use it to code with live checking and compiling without littering my OS. Now, I feel like I'm doing something that already exists but couldn't really find what everyone use, ought of those that would prefer such a setup. Debugger within is probably a pipe dream, but who k…
VS Code is designed to work with these - https://code.visualstudio.com/docs/devcontainers/containers

Maybe nix ( https://github.com/NixOS/nix ) is a better tool for what you're looking for if you're on Linux, you can setup nix shells and work in them, what's installed inside the shell won't be accessible from outside.

I think you missed exceptions often being a problem in low level and embedded targets. That knocks out most of STL anyway. I also think you are a bit harsh on virtual functions - it introduces a single indirection, yes, but sometimes that is fully justified. RTTI on the other hand... of course depends a bit on target characteristics. Perhaps controversial, I've also found (especially bare) lambdas and even std::funct…
You can use quite a lot of STL even with -fno-exceptions. Things that you probably need to ditch are: std::vector std::list std::map std::unordered_map std::set std::unordered_set std::sort std::transform std::merge std::string std::regex std::swap std::function std::stable_partition But there are much more than that in STL.

Sure, there are more embedded friendly libraries, but that wasn't the topic.
One thing that would have helped me when I started learning C++ was learning the C++ compilation model i.e. translation units. It is surprising how many people look surprised (that also claim they know the language) when you tell them that code in .cpp does not get inlined into other .cpp files no matter what doing compilation. (yes the linker can (and should) do that with LTO doing linking)
Compilation units are mainly about symbol visibility and as you already realized at the end of your comment don't have anything to do with inlining as far as the C++ standard is concerned. Neither does the inline keyword btw. The linker doesn't inline anything, LTO/LTCG is about running (part of) the compile process at link time. But that's really no concern for the C++ code but an implementation detail of the toolch…
I get that it is just an implementation detail, but so are many things in C++ and you usually care about these things otherwise you would not be using the language in the first place.
Many projects also disable exceptions that is also an 'implementation detail' (or at least something that is definitely not required by the standard I would imagine), but now you are technically not writing C++ anymore.
I guess this is also one important thing when learning C++. The community is very fragmented, and there seems to be disconnect between C++ users and committee.
What is the C++ job market like? I do mostly Python / web app developmnt, but I don't like the churn.
Having “spent some time in the job market lately”, the salaries seem astronomical if you’re C++ and fintech/HFT. I think some funny business is going on with those listings though… Kinda average in game development and sadly pretty low in embedded systems. All way less common than your average Python position, but probably way more interesting.
I've always heard that they're currently mostly using C++ (and sometimes Java). But I'm not sure how dogmatic or change-averse they are on average.
