C++'s inline is pretty nice, in my opinion. I define an inline function with external linkage, things work as expected (https://en.cppreference.com/w/cpp/language/inline): * taking the address of the inline function works * function-local static objects work as expected (shared across all translation units) * no ODR…
You have seen Foo() = default;. It declares a default constructor (duh!). But what does it really do, and when is it actually useful? "When is it useful" is a very interesting question in my opinion because next time when you see = default; in other people's code, you would understand why…

Compare the following two programs, and can you predict what the outputs would be for each? // program #1 struct Foo { int x; }; void stack() { int x = 3; } void bar() { struct Foo foo{}; cout << foo.x << endl; } int main() { stack(); bar(); return 0; } // program #2 struct Foo { int x; }; void stack(…
std::enable_shared_from_this
[https://en.cppreference.com/w/cpp/memory/enable_shared_from_this] allows a
class to have a valid shared_ptr of this. Simply adding a member function that
returns shared_ptr
You have heard about Coroutine in C++, and you want to use it. There're two coroutine implementations that are considered most mature - cppcoro and folly::coro. They are written by the same guy - Lewis Baker. He's brilliant, and you shoud watch his cppcon talk on structured concurrency [https:…
