你需要知道的最常用20多个C++11新特性¶
1. Variadic Templates¶
2. nullptr and nullptr_t¶
3. Automatic Type Deduction with auto¶
示例:Automatic Type Deduction with auto
4. Uniform Initialization¶
5. initializer_list¶
6. explicit for ctors taking more than one argument¶
示例:explicit for ctors taking more than one argument
7. range-based for statement¶
8. =default, =delete¶
9. Alias (别名) Template (template typedef)¶
10. template template parameter¶
示例:template template parameter
11. type alias¶
示例:type alias
12. noexcept¶
示例:noexcept
13. override¶
示例:override
14. final¶
示例:final
15. decltype¶
示例:decltype
16. lambda¶
示例:lambda
17. Rvalue reference¶
18. move aware class¶
19. 容器-结构与分类¶
- **序列式容器**包括:
array
(C++2.0 新引入)、vector
、deque
、list
、forward_list
(C++2.0 新引入) - **关联式容器**包括:
set/multiset
、map/multimap
- 无序容器(C++2.0 新引入,更换原先
hash_xxx
为unordered_xxx
)包括:unordered_map/unordered_multimap
、unordered_set/unordered_multiset
20. Hash Function¶
21. tuple¶
示例:tuple
22. Spaces in Template Expressions¶
vector<list<int> > // ok in each C++ version
vector<list<int>> // before C++11 error: ‘>>’ should be ‘> >’ within a nested template argument list, C++11 后可以正常通过
