Personally this[1] just makes C much more complicated for me, and I choose C when I want simplicity. If I want complicated, I would just pick C++ which I typically would never want. I would just pick Go (or Elixir if I want a server).

"_BitInt(N)" is also ugly, reminds me of "_Bool" which is thankfully "bool" now.

[1] guard, defer, auto, constexpr, nullptr (what is wrong with NULL?), etc. On top of that "constexpr" and "nullptr" just reeks of C++.

That said, Modern C is an incredible book, I have been using it for C99 (which I intend to continue sticking to).

> what is wrong with NULL?

For starters, you have to #include a header to use it.

And it avoids the NULL == 0 ambiguity, allowing for better type checking.

Well, I always include stdio.h which includes stddef.h that defines NULL as (void *)0.

In my experience, hardly any source files require studio.h

stddef.h on the other hand is required by most to get size_t

You are right. Hereby I correct my parent comment: I talked about my own personal experience[1], but yeah, as you said, stddef.h is often required (and yes, often I do not need stdio.h, stddef.h is what I need) which defines NULL, which was my point. If it is often required, then it does not matter whether you have to include a header file or not, IMO.

Just include the stddef.h header if you want to use NULL, similarly to how you include a header file if you want to use anything else, e.g. bool from stdbool.h.

[1] I am not entirely sure in retrospect, actually, as I might be misremembering, but my point stands with or without stdio.h!
