I'm not going to Google it,so I'll risk my answer: using references & you are safe having something, instead * where you can receive a nullptr. PS: "std::cout" kills my eyes when you included "using namespace std;" some lines before :P

You're sorta right about the ref and pointer only I would add that having a guaranteed something isn't as safe as we would hope, as it could be the wrong something (as shown in one of the examples) and hard to troubleshoot why it is producing the wrong result and not crashing. Unit tests would should catch something like that though. Also, the `using namespace std;` was part of the template, I didn't type that out so I forgot it was even there.
