Unfortunately. If the rank is less than the rank of int, there’s a promotion to either int or unsigned int. It’s a real mess.

I’ll definitely plan to use range views more often, but for now C++23 is (unfortunately?) not an option. For those who are interested, I made an overview of all range views with runnable examples: hackingcpp.com/cpp/std/range…

They might also appreciate this cheat sheet that I made a while ago.
Cheats sheet that visualizes the most common binary representations of unsigned and signed integers and floating point numbers.

same behavior if the first parameter is a string literal (const char*):

I would interpret the relevant section of the standard to mean that the above behavior must be a bug.

Can someone tell me if this highly intuitive behavior is intentional or a quirk of libstdc++'s ranges implementation? Why on earth would you treat a const char* differently from a string_view here? #cpp #cplusplus #cpp20 godbolt.org/z/Kn6ooPzTz

Four new std::string member functions introduced with C++20 and C++23. #cpp #cplusplus #programming #cheatsheet Check out more C++ cheat sheets at: hackingcpp.com/cpp/cheat_she…
Cheat sheet demonstrating the effect of new std::string member functions 'start_with', 'ends_with' and 'contains' that were introduced with C++20 and and 'resize_and_overwrite' that will be introduced with C++23.

I just found out that newer builds of Vim 8.2 as well as the brand-new Vim 9 has a field called 'leadmultispace' for option 'listchars'. vimhelp.org/options.txt.html… See the image below for a quickly thrown-together demo of the effect of the various listchars fields. #VIM #Editor
