Some C++20 ranges aren’t const-iterable

Via StackOverflow:
Newcomers to C++20 Ranges are often surprised that some ranges cannot be “const-iterated.”
But it’s true!

template<std::ranges::range R>
void foreach(const R& rg) { // Wrong!
for (auto&& elt : rg) { }
}

先进的代码生成器，往往只需要朴素的正则表达式

Introduction to Graph Theory

This is a graduate-level introduction to graph theory, corresponding to a quarter-long course. It covers simple graphs, multigraphs as well as their directed analogues, and more restrictive classes such as tournaments, trees and arborescences. Among the features discussed are Eulerian circuits, Hamiltonian cycles, spanning trees, the matrix-tree and BEST theorems, proper colorings, Turan's theorem, bipartite matching and the Menger and Gallai--Milgram theorems. The basics of network flows are introduced in order to prove Hall's marriage theorem.

The style guide must say how to do what you mustn’t do

Consider the following snippets of C++ code. Which ones do you think a good compiler would warn about?

[[nodiscard]] int f();

f();
(void)f();
(int)f();
int dummy = f();
[[maybe_unused]] int dummy = f();
int _ = f();


I recently heard someone complaining…

MSVC Address Sanitizer – One DLL for all Runtime Configurations

With Visual Studio 2022 version 17.7 Preview 3, we have refactored the MSVC Address Sanitizer (ASan) to depend on one runtime DLL regardless of the runtime configuration. This simplifies project onboarding and supports more scenarios, particularly for projects…
