C++11 new feature

It seems that is too later to learn C++11 new feature in 2019. But later is better than never.

  Major new features in C++11

For your interest, here’s a list of the major features that C++11 adds. Note that this list is not comprehensive, but rather intended to highlight some of the key features of interest.

• auto (S.4.8 -- The auto keyword)
• char16_t and char32_t and new literals to support them (no tutorial yet)
• constexpr (4.13 -- Const, constexpr, and symbolic constants)
• decltype (no tutorial yet)
• default specifier (no tutorial yet)
• Delegating constructors (8.6 -- Overlapping and delegating constructors)
• delete specifier (9.13 -- Converting constructors, explicit, and delete)
• Enum classes (S.4.5a -- Enum classes)
• Extern templates (no tutorial yet)
• Lambda expressions (no tutorial yet)
• long long int (4.3 -- Object sizes and the sizeof operator)
• Move constructor and assignment (15.3 -- Move constructors and move assignment)
• Noexcept specifier (quick mention in 14.4 -- Uncaught exceptions, catch-all handlers, and exception specifiers)
• nullptr (6.7a -- Null pointers)
• override and final specifiers(12.2a -- The override and final specifiers, and covariant return types)
• Range-based for statements (6.12a -- For-each loops)
• r-value references (15.2 -- R-value references)
• static_assert (7.12a -- Assert and static_assert) : assert work in runtime, so its args can be var; static_assert work in compile time, its args must be constexpr. A few notes. Because static_assert is evaluated by the compiler, the conditional part of a static_assert must be able to be evaluated at compile time. Because static_assert is not evaluated at runtime, static_assert statements can also be placed anywhere in the code file (even in global space).
• std::initializer_list (10.7 -- std::initializer_list)
• Trailing return type syntax (S.4.8 -- The auto keyword)
• Type aliases (S.4.6 -- Typedefs and type aliases)
• typedef can now typedef template classes
• Uniform initialization (4.1 -- Introduction to fundamental data types)
• User-defined literals (no tutorial yet)
• Variadic templates (no tutorial yet)
• >> will now properly be interpreted as closing a template object

  There are also many new classes in the C++ standard library available for use.

• Better support for multi-threading and thread-local storage (no tutorial yet)
• Hash tables (no tutorial yet)
• Random number generation improvements (basic discussion in 5.9 -- Random number generation)
• Reference wrappers (12.8 -- Object slicing)
• Regular expressions (no tutorial yet)
• std::auto_ptr has been deprecated (15.1 -- Intro to smart pointers and move semantics)
• std::tuple (quick mention at 7.4a -- Returning values by value, reference, and address)
• std::unique_ptr (15.5 -- std::unique_ptr)
