hi,
after reading some articles and faq,
i want to clarify myself what's correct(conform to standard) and
what's not?
or what should be correct but it isn't simply because compilers don't
support.
(first i compiled them with g++3.x. ERR means compiler will bark,
otherwise it does accept it. Then the Comeau C/C++ 4.3.3 comes)

Hi all,
Have alook at two different declarations below:
typedef unsigned char uc;
typedef void (*fptr) (void);
The first declaration has a left part which is a C keyword: "unsigned char"
and the declaration is clarly understandable.

Hi.
Is there any way to define an alias for a type like you could in C++:
typedef int NUMBER;
I tried using #define but that did not work.
Thank you.

Hi,
what is the difference between a "#define" and typedef?
A "#define" is handled by the preprocessor and serves as a name
substitude whereas "typedef" is a declaration of a new data type
based on an exisiting one and handled by a compiler.
So, actually both things are equivalent? Or are there any special
cases where it makes a difference which specifier is used?

I thought I had a fairly good understanding of typedefs until I came across
the following passage from C++ Primer, fourth edition by Stanley B. Lippman:
"The mistake is in thinking of a typedef as a textual expansion" (page 129).
All of my other C++ books and every mention of typedefs that I've seen on the
Internet simply call typedefs a new name as an alias for a type, e.g.
typedef char byte ; // make byte an alias for char (from C++...

I found in C++ a type is typedef several times and alot of time, I
need to dig further to see the original type.
like LPDWORD - it's a strange type, but when i dig further, i see it's
a (DWORD *)
===========
typedef DWORD near *PDWORD;
typedef DWORD far *LPDWORD;

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...
