This is a solid reference for modern C++ that cuts straight to the practical stuff. You get concrete examples of C++20/23 features like concepts, ranges, and coroutines, plus the fundamentals you actually need: smart pointers, move semantics, RAII patterns. The code samples are complete enough to compile and run, which beats hunting through Stack Overflow when you need to remember how to write a proper move constructor or chain range views. It leans heavily on showing rather than explaining, so you'll want some C++ experience already. Best used when you're upgrading legacy code to modern standards or need a quick syntax check on the newer language features without wading through committee proposals.
