You might get output more quickly with a Gemisch. Will you offend the True

The C++ language includes the standard C libraries. Undoubtably, some
of it is written in C, for almost every instance.
So I think C++ programmers can hardly object.

Mix, no. You can call C routines from C++, but not the reverse.

No so, C++ provides a mechanism (the extern "C" linkage specifier) to
make C++ functions callable from C.

Its depend what all you want to do ?
Are you having some code already available in one lang (or both
lang) ?
do you plan to write user/kernel which code ?

Nothing is good or bad if used with care and correct usage.

one can call c from c++, and viceversa.

It is a good thing to get the program finished and running
correctly.

No, it doesn't. It makes C functions callable from C++.

All together now: oh yes it does!
It's commonly used where a C++ function has to be passed to a C library
as a callback.
extern "C" specified the linkage type of the function, not its language.

Programming is a craft more than an art (software engineering, not
black magic) and as such, is about writing code that works, first
and foremost. If it works well, even better. The same goes for
ease of maintenance, memory footprint, speed, etc, etc. Most of the
time, people are writing code for a use in the *real world*, and
not just as an academic exercise.

Hi,
I am new to C and curious to know some basic questions about C.
Why C is good?
In what way its better than any other languages?
If it is no longer a choice of programming language...why people still study
it?
And also its not an OO language either...is there any advantages in being
not an OO language?
I know one reason is that, IT started with C and so they are still using

I want to save tables of integers to files.
One way to write the cells as fixed size in the file, is to use

Is that a bad choice, good choice? I remember once before I posted a program

are there any other ways to write the cells as fixed size in the file?

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.
