== C++ Part==

: new - types - specification and qualification

:: alignas alignof – memory alignment for a variable

:: type-safe enumerations - enum class declaration – not implicitly converted to integers – cannot be compared to integers – underlying type is known - default type is int, can be overridden enum class Enum : unsigned int {vali1, val2} - requires explicit scoping: Enum::val1 – can also use explicit scoping with old-style enum

:: new - expressions

:: raw and cooked User-defined literals – suffix notation – 1234_suffix – numeric literals

:: new - encapsulation

:: default ctor – trivial and non-trivial - POD

:: new - library

:: initializer lists – extends from POD cases to all classes including std containers - initialization-list constructor – T::T(std::initializer_list<type> list) – initializer list is constant and the data in its members cannot be changed

:: tuple types – sets of heterogeneous objects of pre-arranged dimensions

:: hash tables – unordered associative containers

:: regular expressions

:: smart pointers

:: random number facility

:: wrapper reference

:: polymorphic wrappers

:: type traits for meta-programming

:: computing return type of function objects

:: new - compatibility with C

:: plain old data – relaxed restrictions POD rules – trivial and std layout

== C Part==

:: new - add to align with C11

:: _Generic( ) - type-generic macros

:: complex data type

:: macros for construction of complex values

:: alignment specifications (_Alignas, _Alignof())

:: _Atomic

:: _Noreturn

:: macros for floating-point characteristics

:: quick_exit() (if exit() fails)
