Complex numbers don't seem to me that widely used. But still C99 introduces not one, but two keywords about them (_Complex and _Imaginary). To me it seems that those belong in a library, and possibly not even the standard library.
Why are complex numbers so important to the standardization committee of the C language? More important than pixels, 3D points, files, time.

I have learned in class that driving a car is considered as partially because AI can't know what the other driver's emotion is nor what is around the corner. Or in some case chess, it is fully observable because the AI can see both AI's piece and opponent piece. But what about knitting? does it need to see around its own environment? is it deterministic because there's no miscalculation?

Most of the pre-commit check tools I have used with different organizations do not allow whitespace at the end of lines. What is the motivation for this? Can it cause different behaviour, increase flash memory usage, or is it just a stylistic thing?

At my university, my CS1 teacher has advised us to not use for(int i = 0; [code]; i++), because declaring a variable in line with a for loop will not compile on C versions prior to C99. As a computer science major, is there any legitimate reason for this? As it was standardized nearly two decades ago, I would think any still supported / developed software would have no trouble implementing this.
From my browsing it appears that extremely low level hardware development such as the Linux kernel may use a C90-ish codebase but that seems to be a very fringe case.

If you see the gcc source code, you see that they use macros a lot. But generally, programmers are advised to avoid macros as they make the code harder to read.
Why then the gcc devs use so much of macros?
Please provide advice on when to use macros and when not to use.
Any references are welcome.

I would like to parse a html page and extract the tags from it. I need suggestions on some good algorithms to do this in C? I have tried looking for libraries but most of them seem to support python, ruby or java but sadly nothing is there for C.
try using HTML tidy
