I was wondering if anyone knew of a way to use std::copy() and
istream_iterator<>/ostream_iterator<> write a file copy function that is
quick and efficient.
Doing this messes up the file because it seems to ignore '\n'
ifstream in("somefile");
ofstream out("someOtherFile");
std::copy(std::istream_iterator<unsigned char>(in),

Hello,
Could someone explain to me why the Standard conveners chose to typedef
std::string rather than derive it from std::basic_string<char, ...>?
The result of course is that it is effectively impossible to forward declare
std::string. (Yes I am aware that some libraries have a string_fwd.h header,
but this is not portable.)
That said, is there any real reason why I can't derive an otherwise empty

Hello,
For many years ago I implemented my own string buffer class, which
works fine except assignments - it copies the char* buffer instead of
the pointer. Therefore in function calls I pass "const char*" and get
the result in a parameter by reference "MyString& result".
I'd like to move to nicer strings. In order to keep platform/compiler
independence I consider std:string as the replacement. While googling
I managed to read some...

Hi,
I have written this code, and at the end, I am trying to write a
vector of strings into a text file. However, my program is nor
compiling, and it gives me the following error when I try to write to
the file:
error C2679: binary '<<' : no operator found which takes a right-hand
operand of type 'std::string' (or there is no acceptable conversion)
I don't know what I am doing wrong. I have posted my entire program

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...

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,...

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...
