> What is C++ uniquely good for in 2017? C++ is special because it combines two big ideas: - Zero-cost abstractions (you only pay for what you use) - High-level abstractions (OOP, lambdas, code-generation, etc. ) I would jump straight to C++ 17. It looks completely different to early 2000s C++ and makes functional programming easier (type inference, lambdas, constexpr, etc. ). If you learn to use C++ well, you will be able to write faster code faster.

Zero-cost abstractions (you only pay for what you use) True in theory and essentially because C++ still remains mostly a superset of C, but unfortunately the majority of C++ programmers I've met tend to overabstract and not realise it, making this claim not really true in practice. High-level abstractions (OOP, lambdas, code-generation, etc. ) On the other hand, this is definitely true in practice.

  > "C++ still remains mostly a superset of C" I think this notion is out-of-date. Have a look at this slide: https://youtu.be/_wzc7a3McOs?t=21m37s https://youtu.be/_wzc7a3McOs?t=21m37s It shows how C++ has evolved away from just "C with Classes". I agree that many C++ programmers over-abstract things.

    It shows how C++ has evolved away from just "C with Classes". I meant that C code, with few modifications, will basically work fine when compiled with a C++ compiler.

  The way it works out in practice is people can develop at a high level, and then when its needed you can go back and refactor where necessary for perf. The average performance does become slower though.

> I would jump straight to C++ 17. I'd love to, but there are simply no (accessible?) resources. I'd love a "how to write C++17 with no baggage" book, but it simply doesn't exist. (please, correct me if I'm wrong?) I really want to get to know C++, it looks like it's become a fantastic language, but in all seriousness, I could write fast, performant robust Go within a weekend, I'm proficient in half a dozen other languages, and C++ programmers still unironically suggest a stack of books the height of a small table to beginners.

  I don't own it, but this book sounds like it may be what you're after: http://www.bfilipek.com/2017/06/modern-c-programming-cookbook-review.html http://www.bfilipek.com/2017/06/modern-c-programming-cookboo...

    Thanks for the link it looks promising: The Book is intended for all C++ developers, regardless of their experience. The beginner and intermediate developers will benefit the most from the book in their attempt to become prolific with C++. Experienced C++ developers, on the other hand, will find a good reference for many C++11, C++14, and C++17 language and library features that may come in handy from time to time.
