Hi,
I want to control the output such that it always print at the same
line, erasing the line just printed (or erasing a particular posistion at a
certain line). Say, for a simple program like this,
#include <StdAfx.h>
#include <iostream.h>
void main() {
cout<<"Hello World"<<endl;
cout<<":) " <<endl;

Is it true that cin,cout, etc are initialized on first use? And that no runtime initialization before main is needed; the first time the object is accessed, it grabs dynamic memory typically like 1K of memory?
Thanks

I want to create an object,
which replaces std::cout
all output will be put out to std::cout, but optional
also copied to a file.
But the file output needs to be manipulated:
every new line has to be preceded by a ';'
Is there an easy way to do so?
Or do I have to write wrappers for all kind of

In one of my applications, I was mixing perror (cerrno )with
cout(iostream) calls and sometimes getting unordered output. The exact
context was to print an error condition as well as cause for
exceptions. Therefore, I resorted to .flush call in iostream that did
the trick. Anyone can explain the root of all evil in intermixing the
c++ with date c library, perhaps, give a link to where solutions to
this problem are addressed?
Why...

Hello experts,
are cout and printf and other ostream and stdio functions/libraries are
threadsafe?
i am using gnu gcc3.3.2 on AIX5.2.
and my applications are multithreaded applications.
i am using -lpthread as one of the compiler option.
i am using cout and printf for debugging purpose.
thanks for ur replies in advance.
Thanks and Regards

I have a C++ console program which has a lot of output (no input) like this:
cout << "Strings here".
Now i want to turn this application to windows application (with gui) and I
want to bring the output of
cout << "string" to a rich text box. Because of a great quantity of cout, i
don't and can't change each cout << code.
I need some mechansim (like pipe or hook into << command) to direct the
output of cout << into the rich text box....

Hi!
Could someone explain to me why this operation is not what I was expecting?
int main()
{
int x = 2;
std::cout << x << " " << x++ << std::endl;
return 0;
}

Hi,
can I mix output to cout and wcout? It seems that if I write to cout
first it works fine but if I start with wcout the output to cout
vanishes. I assume that is has to do with the initialization of
standard output, right?
#include <iostream>
using namespace std;

why when I use cout, I must put - using std::cout;
#include <iostream>
using std::cout;
if i look at iostream, it seem cout is defined in iostream -
__PURE_APPDOMAIN_GLOBAL extern _CRTDATA2 ostream cout;
I also see
_STD_BEGIN

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
