►Lesson Description: In this lesson we take a look at std::cout, a globally defined object that has been around for a long time in C++. But why do we still need it if we have std::print in C++23? Certainly for legacy code it is useful -- but in this lesson I try to explain that std::cout is a 'stream' type that allows us to write out information. We can build our own useful abstractions with this type, and thus it is just a different model for writing out data. You can still use it with things like std::format to get the best of both worlds as well. Let me know which you prefer and the trade-offs you have heard between std::cout and std::print! As always, feel free to bring up any questions and discuss what you've learned!
