That is true, though in the real world (existing codebases) you encounter old, new, modern and novel styles of C++. So in order to understand the used forms of something that should be simple, like printing, you will need to know at least 4 different ways of coding it. That is somehow the frustrating part of the language, there is no 'right' C++. Kudos for those who are willing to dig deep enough to fully understand const correctness, smart pointers, dynamic casts, double referencing, every type of formatting and template programming. Though sometimes I think there is some masochism involved...
