Seperate compilation (that's what it's called, right?) seems to be
quite popular, so I decided to get some info about it, and (d'oh) use
it...
But it's whole structure seems weird to me...
Here's what I think of how it is (from what I've read):

I'm learning C++ after having spent several years in the computer industry
doing both system administration and engineering. I've written code in
Perl, Bash, Pascal, Ada, C, Mathematica (hundreds of lines of OO code, not
1+1), JavaScript, Lisp, and Java, as well as C++. Each of these languages
has it's strengths and weaknesses. My experience with C++ has shown me
that it is by far the most difficult for me to learn.
I have the sense...

I just started learning C++ on my own...I'm using Accelerated C++.
Something it hasn't explained and I keep wondering about is how header
files actually work. I suspect it doesn't get into it because it is,
as the authors love to say, "implementation specific". If that's the
case, how does the compiler commonly handle them? I use Linux and gcc
specifically. Basically, I don't understand how a header file being
included makes a...

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 understand it.

Suppose i have created a class c1 with f1()in c1.cpp
and included this c1.cpp in file1.cpp file , which is also having
main() by giving the statement #include "c1.cpp".
the same i can do by using header file. i can create a class c1 with
f1() in c1.h and include this c1.h in file1.cpp by giving the statement
#include "c1.h"
tell me that what exactly is the difference between c1.h and c1.cpp?
Since they both are doing the same things.

Iam just trying to know "c".
And I have a small doubt about these header files.
The header files just contain the declaration part...Where is the
definition for these declarations written??And how does that get
linked to our program when we run it??I would appreciate any helpful
info..And I would like to thank you for that in advance

Hi all
What does the group think of the practise of including one header file from
inside another?
I have some legacy code where this has been done, and it creates a
dependency on a module (collection of files) which are not required, except
for one header file's contents.
I'd say 'No, header files should be included in the C source, not in another

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 know, the definition of a class is always in a
header file. And we can use "#ifndef" to eliminate...

Hi,
I have few doubts about header files.
Is it true that header files always have only "function declaration"
and not definition?
Next where can i find definition of functions defined in system header
files. I'm working on UNIX.
Thanx in advance.

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:

Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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. For most users, this new feature is actually very convenient. If you want to control the update process,...
