# C++新特性
|
||
|
||
## 1.C++11新特性
|
||
|
||
- [Variadic Templates](./variadic)
|
||
|
||
- Spaces in Template Expressions
|
||
|
||
```cpp
|
||
vector<list<int> > //ok in each C++ version
|
||
vector<list<int>> // before c++ 11 error error: ‘>>’ should be ‘> >’ within a nested template argument list,c++11后可以正常通过
|
||
```
|
||
|
||
- [nullptr and nullptr_t](./nullptr.cpp)
|
||
|
||
- [Automatic Type Deduction with auto](./auto.cpp)
|
||
|
||
- [Uniform Initialization ](./uniform_initialization.cpp)
|
||
|
||
- [initializer_list](./initializer.cpp)
|
||
|
||
- [explicit for ctors taking more than one argument](./explicit.cpp)
|
||
|
||
- [range-based for statement](./auto.cpp)
|
||
|
||
```cpp
|
||
for(decl:col) {
|
||
statement
|
||
}
|
||
```
|
||
|
||
- [=default,=delete](./default_delete.cpp)
|
||
|
||
如果你自行定义了一个ctor,那么编译器就不会给你一个default ctor
|
||
如果强制加上=default,就可以重新获得并使用default ctor.
|
||
|
||
- Alias(化名)Template(template typedef)
|
||
|
||
- [alias.cpp](./alias.cpp)
|
||
- [template_template.cpp](./template_template.cpp)
|
||
|
||
- [template template parameter](./template_template.cpp)
|
||
|
||
- [type alias](./type_alias.cpp)
|
||
|
||
- [noexcept](./noexcept.cpp)
|
||
|
||
- [override](./override.cpp)
|
||
|
||
- [final](./final.cpp)
|
||
|
||
- [decltype](./decltype.cpp)
|
||
|
||
- [lambda](./lambda.cpp)
|
||
|
||
- [Rvalue reference](./rvalue.cpp)
|
||
|
||
- [move aware class](./move.cpp)
|
||
|
||
- 容器-结构与分类
|
||
|
||
- (1) 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)
|
||
- (2) 关联式容器包括：set/multiset,map/multimap
|
||
- (3) 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
|
||
|
||
- [Hash Function](./hash.cpp)
|
||
|
||
- [tuple](./tuple.cpp)
|
