Hi,
I am trying to use boost::range with one of my own container class,
and having some problem.
I am missing some usage of range. Can anyone suggest a proper way for
it ?
To show the problem I am facing, giving a small test program to
demonstrate .
typedef vector<intVI;
VI v; //vector of int.

First of all: distinction of keywords typename and class in template
arguments.
Accoarding to a post in a well known moderated group:
"There are three possibilities for template arguments:
1) type as in "template <typename T>" or "template <class T>"
2) non-type as in "template <int N>"
3) class template as in "template <template<typenameclass C>" "

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>

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....
Now, this would greatly impact the work of software developers. The idea...
