Given this program, compiled with g++-13 -std=c++2b test.cpp: ...where that is... #include <array> #include <ranges> auto main() -> ...
I am trying to implement a function that calculates the Cartesian product of ranges. I know there's views::zip and views::cartesian_product available, ...
I am trying to create a function that will initialize an internal std::set<std::string>, and I want to expose an API that allows any type of ran ...
Consider the following example: int main() { std::string_view foo = "This is a test"; auto split_foo = foo | std ...
Legacy iterator adaptors such as reverse_iterator and move_iterator, or C++20/23 newly introduced adaptors such as counted_iterator, basic_const_itera ...
I'd like to achieve something like this: mycallback() should accept a C++20 range of integers. To be more specific I'll need owning_view with misce ...
Godbolt: Here input is a contiguous, non-common, non-sized range. range-v3's take_last(n) doesn't work on such ranges, because its strategy is simp ...
I am trying to get into ranges::views. The following demo program does not compile: Error messages: I am using "Microsoft Visual Studio Communi ...
I am looking for a way to do a binary search over function results with a signature close to the following: The function is expected to return a fi ...
The output: Did you notice this second 4 in the second output? How did it end up there? It seems that happened due to even.begin() has been cache ...
Why is constness of lvalue reference completely ignored if an argument of a function is of type std::view? Edit: If, as you wrote in the comments, ...
I want to create a view that will have views of both halves of the string. I added some code examples of what I would like to achieve. How could I do ...
Sorry, I was searching a lot, but I still do not understand. Let's assume that I want to read line by line with an istream_view using a line proxy an ...
Goal is to minimize a function over a range of input values. Performance matters. Unfortunately, the ranges::min() algorithm recomputes the output for ...
Using g++ with -std=C++20 or later, the following compiles (assuming vec is a vector of appropriate type): but the following does not (wrong number ...
There is a rather typical task of sorting two arrays simultaneously, assuming that same indexed elements of the arrays form virtual pairs, which are s ...
I am currently reading about the range library. My question is about resource ownerships when using views, and how to use these safely. Let's conside ...
In C++23, the ranges (sub)library has gained std::ranges::zip, which zips multiple ranges into a single range of std::tuple's (or pairs). This is nice ...
I wonder if the std::ranges::* algorithms should be working with std::initializer_list. For example, line (B) in the following snippet compiles while ...
