Neu in C++11 https://en.wikipedia.org/wiki/C%2B%2B11

1. Templates

   • Nicht mehr wegzudenken
   • Performance
   • "Generics"

"With respect to C++, the syntax and idioms of template metaprogramming are esoteric compared to conventional C++ programming, and template metaprograms can be very difficult to understand. [6][7]"

  • http://en.cppreference.com/w/cpp/language/type_alias
  • http://en.cppreference.com/w/cpp/language/template_argument_deduction

  a) static_assert (http://en.cppreference.com/w/cpp/language/static_assert) b) type traits (http://en.cppreference.com/w/cpp/types)

2. Type inference Auto & decltype (https://en.wikipedia.org/wiki/C%2B%2B11#constexpr_.E2.80.93_Generalized_constant_expressions)

3. Lambda functions & Expressions capture -> return_type { function_body }

• https://en.wikipedia.org/wiki/Anonymous_function#C.2B.2B_.28since_C.2B.2B11.29 https://stackoverflow.com/questions/7627098/what-is-a-lambda-expression-in-c11

4. New function syntax auto funcname(parameters) -> return_type { function_body }

5. Uniform initialization and Object construction - new type_name{} - delegate constructors (members, this(), super() via using)

6. Strong typed enumerations - Enum classes

7. Type/Template aliases using type_name = other_type

8. (Custom suffixes)

9. (= default and = delete)

10. (Attributes)

    int [[attr1]] i [[attr2, attr3]];

    [[attr4(arg1, arg2)]] if (cond) { [[vendor::attr5]] return i; }

    [[deprecated("g() is thread-unsafe. Use h() instead")]] // C++ 14

11. Zusätzliche Konstrukturtypen: Move Constructor, inherited and delegating constructors https://blog.smartbear.com/c-plus-plus/c11-tutorial-introducing-the-move-constructor-and-the-move-assignment-operator/

12. CPP Core Guidelines https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md

13. Zukunft CPP = Boost Library http://www.boost.org/

14. RAII - Smart Pointer - http://en.cppreference.com/w/cpp/memory/unique_ptr/unique_ptr
