Hello,
I have a class with constructor taking a const string&. Now i want to
call this constructor with a string literal. Because this is of type
char* there are overload resolution conflicts.
If i make another constructor with parameter const char*, how can i
call the constructor with the const string& ?
I tried

I have heard it is considered good practice to pass function parameters as
const& as often as possible, is this true? Is it possible to go overboard?
And if so why? Thanks a lot in advance everyone!

If i want call my func with func("blah") i could write:

After more searching I found that defining const operators
can cause problems with many compilers due to the way it
interprets the C++ standard. I removed the const
operators from my class and it seems to be working fine
now.

Just looking for opinion on which of the 3 methods below people use in
their code when they convert a 'const char *' to a 'const std::string
&'
came across #3 in someone's code and I had to think for a sec. At
first I read it as converting a 'const char *' to a 'std::string *'
void f(const std::string &s)
{
std::cout << s.size() << "\n";

I have a lot of functions returning "const std::string&". Every time I
wrap one of those I have to do it like this:
class_.def("name", &someclass::bla,
boost::python::return_value_policy<boost::python::copy_const_reference>()
);
Is there a way to register a return value conversion for "const
std::string&" so I can omit it every time I have to wrap functions
returning "const std::string&" ? I wan't those strings to be copied to

Hi
I have created a simple function called 'addTheString(string& str,
string appstr)' and the intension
is to append the 'appstr' to 'str' and use 'str'.
I tried swigging this method. My swigtest.i file is okay as I think
I have added both
- stl.i at top
- std_string.i

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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....

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...
