Hi,
I'm trying to do fscanf from a file with integers.
I've tried using both %d and %i hoping that I would figure out their difference.

i: Matches an optionally signed integer ...

Forget the exact definition of difference between,
#include <foo.h>
and
#include "bar.h"
Normally foo.h is a standard header file, so it's path is not defined
in compiler option, but I am curious how compiler find it.

Hi c++ Gurus,
Need your blessing.
while testing few aspects with respect to header file inclusions, i
observed few things which i would like to share with you.
i have a file sqlca.h in which a structure sqlca is declared.
i included this file as a soft link in /usr/include.
the soft link is as follows:
sqlca.h -> /usr/opt/db2_08_01/include64/sqlca.h

Dear All,
I saw some people using
#include <string.h>
some people using
#include <cstring>
What is the difference between the two? I can find the file string.h at
/usr/include. I don't know if cstring is a file and if so, where to find it.

Hi,
This is just a generic question, where i want to know what is the
difference in including a header file in a .h file and .cpp file.
I have a class called MyClass (MyClass.h & MyClass.cpp).
There is another class (OtherClass.h & OtherClass.cpp)
OtherClass.cpp has a forward declaration to a class called 'Calc' which
is in the namespace called 'Utils' like below:

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...
