The C++ programmers here disagree given how often they point out that C++ close to the machine is actually the C style of programming done with C++ language. It&#x27;s actively discouraged by the C++ community in favor of the C++ style of programming described in Modern C++, etc. The C++ style gives low-overhead abstractions that increase safety and maintainability (in theory) while aiming for C compatibility and performance. Main libraries and well-written apps are big on metaprogrammed constructs.<p>So, learning to code professional C++ will not help you understand machines more. You&#x27;d have to learn C, basic OS&#x2F;CPU structures, and which compilers produce for certain C statements. Maybe read Write Great Code by Hyde or some online articles. Learn C++ to understand machines? Not happening unless you microprogram a CPU for it on a FPGA.
