C++ needs to be able to do that because there's no good way to return multiple values
return std::make_tuple(pow(x, 2), sqrt(x));
auto t = square_and_sqrt(9);
std::cout << std::get<0>(t) << "\n"

I'm having a small problem with how I alter the attributes or even variables in called functions. To change them globally, I understand you can just declare them as global with the global keyword, but is there any other ways to do this? I don't want to make a lot of variables global.
