If we go through the list of C++23 features, we can stumble upon the notion of garbage collection twice. Once among the language and once among the library features. Both entries refer to the same paper (P2186R2): garbage collection (GC in short) support is getting removed from C++. Just to make it clear, it’s not…
Let’s start with a question! Is this program well-defined? 1 2 3 4 int main() { while (true) ; } If you said yes, you’d be wrong — at least before C++26. A while (true); loop with no side effects used to be undefined behaviour. Compilers were free to assume it terminates, and some — Clang in particular — would…
C++26 brings us a small but meaningful cleanup to the language: deprecating ellipsis parameters without a preceding comma. This change, proposed in P3176R1, aims to improve C compatibility, reduce confusion, and pave the way for future language features. The proposal’s name is a playful reference to the Oxford comma …
If you’ve ever needed to hit a breakpoint programmatically in C++, you’ve probably written something like this: 1 2 3 4 5 6 7 8 9 #if defined(_MSC_VER) __debugbreak(); #elif defined(__clang__) __builtin_debugtrap(); #elif defined(__GNUC__) && (defined(__i386__) || defined(__x86_64__)) __asm__ volatile("int3"); #else…
