An Overview of C++11/14, Part I
summary
Survey lists concrete language changes and shows code that compiles: uses auto and decltype for return types, rvalue references and move semantics for performance, and variadic templates to implement sum/average at compile time. Demo replaces manual iterator typedefs with non‑member begin/end, uses nullptr, range‑for, static_assert, conditional noexcept, extern template to cut object bloat, and constexpr enhancements in C++14. Slides and source materials live at https://github.com/CppCon/CppCon2014 and the examples are tested and runnable.
