Easier C++ Hello World

Writing Hello World in C++ has never been easier auto& hello(std::ostream& os) { return printf("Hello, World!\n"), os; } int main() { std::cout << hello; }

A screenshot presents a clever C++ implementation of “Hello, World!” where a function returns the output stream after calling printf, allowing it to be passed directly to std::cout. The joke is that a traditionally simple beginner program is made unnecessarily elaborate, while humorously claiming this is the easiest way to write it.
