At first I thought they were heredoc, but, that obviously wasn't the case. My next guess is that they were some sort of strict comparison === is more strict than ==, so I figured >> is more strict than >. That wasn't the case either. After wondering for a while what it could be, I decided to look it up. It ends up that you use it to output text. cout << "Hello World"; It was SO confusing, because they also have printf which can be used to output text. I decided that c++ is obviously a garbage language and gave up.
