I wouldn't consider that anything close to beginner-level C++ because, as you said, it bombards you with a ton of concepts all at the same time. It's the kind of thing that I'd want put into some library and not look at it. All that I'm trying to advocate are things like smart pointers instead of raw pointers and relying on iterators so you can use range-based for loops. Avoid some of the classic problems like forgetting to de-allocate things, de-allocating twice, using out-of-range indexes, and all that.
