Hello,
I would like to know what the C standards (and in particular the C99
standard) have to say about union initializers with regards to the
following code snippet (which compiles fine under gcc 3.2.2 but
does not produce the expected results, the expected results
being the ones annotated in the comments in the code):

Hi,
I will write ANSI C89.
Is the following struct defenition correct ?
I wrote it with VC6(Windows IDE) and at first no Problem.
As I changed a compiler switch to 'no language extension',
the compiler said that the union has no name.
Is it right that in ANSI C the union must be named inside this kind of
structure ?

Dear ALL
As we know that when we declare the union then we have the size of the
union which is the size of the highest data type as in the below case
the
size should be 4 (For my case and compiler), and it is,
what I conclude from the below code

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
