I've noticed a lot of people preferring std::cout over cout. May I ask why
you prefer one over the other?

Is std::cout slower than printf
When we call printf e.g. in
printf(20 format conversion specifications, 20 arguments);
Is it faster than the
std::cout << { 20 redirections to the output stream }

Hi,
I am using std::cout to print a char pointer that is NULL. Subsequent
calls to std::cout dont print anything. Is this the expected behavior?
example:
#include <iostream>
int main( int argc, char *argv ) {
char *q = 0;
std::cout << q << "\n";

What is the correct portable way of outputting binary data to cout? I
know that I can call _setmode(1, _O_BINARY) but that only works for
MSDOS.
And I *have* tried to Google it, but I have not been able to produce
any working code from what I found. Could anyone please extend the code
below, so that it writes binary data to cout without...

Hi, everyone
It might be a simple question, but I really don't know the answer.
char c = '1';
cout << c;
The above code will only output a '1' rather than 0x31;
If I use int cast, it can show the number:

Hello, I'm pretty new to C++ programming, and I'm teaching myself the
language using various sources.
This sounds stupid, but I am really confused on this... I was
wondering why we have to write a C++ program with this:
#include <iostream>
using std::cout;
using std::endl;

Is it possible to save a copy of cout the same way you can save a copy
of stdout in C (I know C version is portable, but unix portable is
good enough for me).
I have to use a library which closes stdout on init because its used
to mostly in background processes but I need it for an interactive
process. Library cant be changed unfortunately....

I'm getting back into C++ after a long hiatus (they didn't have
namespaces back then).
I know this question is completely subjective, but I'd be interested in
hearing which is
the "better" style and what the pros and cons are (I'm using cout as
example, but it really
applies to any similar construct):
1) using std::cout;

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. ...
