comes when its for multidimentional arrays.I have read the C faq but

I wonder if anyone can help me, I've been headscratching for a few hours

Hello all,
I was wondering if there were some sort of limitations on the "if"
statement? I'm writing a program which needs to check a bunch of
conditions all at the same time (basically). And I'm pretty sure the
rest of the program is working just fine. The only thing I could think
might be wrong is that the if statement can only hold so many values in
itself? Let me show what I'm doing:
if (table001]>>5]&b&0x1f] != 0 &&

is just useless. It can be showed by my program:

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
Here is the code in...
