In the past there have been lengthy discussiions regarding the role of
header files in C++. People have been very adamat about header files
serving as in interface to the implementation. I do understand the
objective. This example may represent an interface in need of a bit of
refactoring, but it goes to demonstrate the basic idea as I...

A problem I've been rather stuck on and, try as I might, have not been
able to find the answer to.
I've written a nice little class that I want to include in another
project. The class works fine if I have it all in one big file, but I run
into problems when I try to break it down into source and header files. I
get a linker error when I...

Suppose i have created a class c1 with f1()in c1.cpp

It seems like, in every C source file I've ever seen, there has been a
very definite include order, as follows:
- include system headers
- include application headers
- include the header associated with this source file
For example, in a file hello.c:
#include <stdio.h>

I'm kind of new to creating templates. I've made some small class and
function templates in the past and I have used quite of bit of the STL,
but I am having problems tyring to create templates.
I'm trying to make class templates in seperate header files with
pointers to each other, and I am getting strange errors.
Is it possible to do?

Hi
is it right to have a line like
#include <path/to/header.hfor a library on my system, in my header
file and use some functions provided by this library in the
implementation file (file.cpp) inside a class with out declaring those
functions in the class declaration in the header file?
thanks

Stanley B Lippman in his "C++ Primer" that a definition like this
should not appear in a header file:
int ix;
The inclusion of any of these definitions in two or more files of the
same program will result in a linker error complaining about multiple
definitions. So this kind of definition should be avoided as much as
possible. But as we...

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. ...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
