and neither seems to work most likey its me since I am getting frustrated.

I use this function that I wrote for inputting strings. It's meant to
return a pointer to mallocated memory holding one input string, or 0 on
error. (Personally, I prefer to use 0 to NULL when returning null
pointers.) It looks pretty watertight to me, but my version of lint
complains about use of deallocated pointers, etc. Is this code
completely safe on all input, or have I missed something?

I'm trying to find some nice, concise code that asks the user for their
name and then stores it. I'd like it to behave as follows:
1. The user can type in up to 12 letters or numbers

mistake then they can delete letters using backspace
4. The code only saves...

I have a fully-portable C program (or at least I think I do). It works
fine on Windows, but malfunctions on Linux. I suspect that there's
something I don't know about the standard input stream that's causing
the problem.
Here's how I wrote the program originally:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
