Here's rust code:

    fn main() {
        println!("Hello, world");
    }

Here is the equivalent C++ for the vast majority of its life (any time before C++23, has MS even shipped C++23 support yet?):

    #include <iostream>

    int main() {
      std::cout << "Hello World!" << std::endl;
      return 0;
    }

C++ initialisation alone is a more complex topic than pretty much any facet of Rust. And it's not hard to find C++ which is utterly inscrutable.
