I have been using C since around 1978.

The original manual (which I still have), "A Programmer's Work Bench" is
clear about its intended audience and purpose, it is aimed at system
programming and as a replacement for assembly language, a portable
assembler.

I also have multiple articles from the Bell Labs Journals. All, however
written for an audience with advanced engineering and/or math degrees (a
Bell Labs MTS) and are not particularly useful for general consumption.

I taught C programming at Bell Labs and AT&T and in Universities after
retiring. I have also written a considerable amount of code, mostly for
embedded system and OS core service.

In my opinion, most people who code should not be using a language that
allows for pointer access, pointer arithmetic, and the other low level
access and side effects that are built into the language. That said,
there are to my knowledge no good Algol based languages in common use.
Pascal and its progeny (Modular, Modular-2, Modular-3) never caught on
and the original Iron Man became a horror of complexity as Ada. The
current P-Code languages such as Python and Java are, for me, too slow
and exhibit an annoying syntax. Propriety languages such as PL/I could
have succeeded if their parent companies had released them into the
public domain.

Therefore, I guess C is all that is available for coding ELF
applications. As such, I would strongly recommend reading all one can
find on the Internet. Every C book I have reviewed that is reasonably
understandable leaves out or glosses over some of the truly useful
language constructs. What is most often missing are proper use of a
union rather then casting, the use of an atexit stack and signals for
minimizing crashes, the extensive memory monitoring library and the
ability to start the program prior to main() so the signal masks and
memory monitors can be started prior to the operational code.

I still have the syllabus from the undergraduate class I taught. Its
badly out of date but perhaps I can update it and post it on some public
forum.
