Above things had been comeing from the usual methodology, and we can derive out some more detail from ISO 26262-2018, chapter 6 for the unit design and coding methodology:
Here in C++, the 1a~1i can be used as guidance, following is some illlustration:
①enforcement of low complexity, applied in ASIL A~ ASIL D, describing more in the coding complexity, like no bigg function designs, complex coding structures;
② use of language subsets, shall be clear defined, lesson learned the good practise, and run-time error or real time errors shall be avoided;
③ strong typing not in specialty in C++, but for all of the languages, C language has this kinds of problems, and C++ will be better, as well in C++ library, but we have to as well discuss more about this topic.
Thank you for the reading, and any comments we can discuss further.
