A presentation -- I gave -- aimed at building a healthy mental model of C++, without detailing the many dark corners of C++; it starts from the basics and ends at an intermediate level - thereon the viewer can comfortably pursue learning the language from more formal sources.

The slide deck, loaded with links to official sources to justify the claims made, can be viewed on a mobile too :)

Of course, this is my opinion of how to build a good mental model. Your's might differ. Any comments, suggestions, feedback or pull requests are welcome.
