Hello all... I get an error message for the following program by the
compiler:

#include <string>
using namespace std;
ostream_iterator<string> oo(cout);

a std::ostream_iterator can be constructed from a ostream but not a fstream.
If the fstream is opened with the out mode how can I get a ostream_iterator?
I am not using a pointer to any base class.

std::copy to std::ostream_iterator doesn't seem to
work with maps and pairs.
Shouldn't I expect something like this to work?
The G++ error message when USE_COPY_TO_PRINT is
defined as a non-zero number follows.

consider the following:
ostream_iterator<int> i(cout,"");
cout << setw(3);
copy(int_list.begin(),int_list.end(),i);
the problem is that the field width restriction is only active for the first
element of int_list. after the first element is copied to cout the stream
setw(3) no longer has any affect.

Hello,
Can any one get the 'copy' statement below to work? I want it to
do the same thing as the 'for' loop does. But I got a lot of STL error
during compile.
Thanks,
Nan

Hi,
Can someone tell me why I always get an error like "`ostream_iterator'
undeclared (first use this function) " when using ostream_iterator. I
have for example tried the following code taken from
http://www.camtp.uni-mb.si/books/Thinking-in-C++/Chapter04.html :
//: C04:Intset.cpp
// Simple use of STL set
#include <set>

I cannot compile the code which defines a std::map type consisting of
built in types and operator<< overload for std::map::value_type.
See the code below - I attach a full example.
Note: if I define map type with my new type (structure) everything is
OK. All compileres I've cheked report an error so I think it is a
problem with my code.
#include <algorithm>
#include <cstddef>

I'm trying to use an ostream_iterator to iterate over a set of pairs.
I've used an ostream_iterator over other types and had no problem.
However, with the following code snippet, I'm getting a compiler
error, and I'm stymied as to why. It's seems to be related to the
string type, because iterating over pairs of other types has worked
fine for me. The (rather verbose) error is:
/usr/include/c++/4.2/bits/stream_iterator.h:196: error: no...

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...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
