I'm really starting to believe that there's a cohort of modern programmers that only see programming languages in terms of the high level syntactical features they provide. The logic of it is something like: I write the code, I run a command written using similar code, scenes deleted, my program runs and my IDE tells me if there are problems in my code. This is sometimes defined as the difference between developers a…

It was already irrelevant when using MS-DOS with Turbo Pascal/Modula-2/Basic compilers, or Mac OS (originally written in Object Pascal/Assembly). It was UNIX industry adoption, followed by GNU Manifesto that made to more relevant than it should ever have been.

In C it's possible (and, to some level, very much encouraged) to write your own things to replace whatever built in thing you don't like for whatever reason, be it speed, size, portability. C not having fancy built-in structures means programmers are more careful about choosing simple ones, which dramatically cuts down the amount of completely pointless generated code. -O3 can optimize registers and maybe memory read…

You should be worried about those way before the occasional vector push reallocation cause you any problem. (And you can specify initial capacity so there is that)

Adding so-called fat pointers to C that could be bounds checked would probably instantly eliminate a large fraction of all security issues. Of course, you can emulate these yourself, it's just a struct but not everyone does.

C99 introduced variable-length array parameters and variable-length array pointers together with variable-length arrays (VLA). These take another parameter or variable as a length-parameter. These became optional in C11 together with VLAs (for some reason) but are supposed to again become mandatory in C23. However (yet, for some reason) the pointers can (in the latest published draft, still) only be inside procedures…

Finally C catches up with Algol 60 boolean types, it only took 60 years. Maybe in another 60 it will get proper strings and arrays.

Then it would become Algol, wouldn't it?

So many features still missing.
