### 2.[C++2.0新特性](./c++2.0)
#### 2.0 概况
C++2.0简称包括C++11/14/17/20。
#### 2.1 [C++11新特性](./c++2.0/c++11)
- [Variadic Templates](./c++2.0/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](./c++2.0/nullptr.cpp)
- [Automatic Type Deduction with auto](./c++2.0/auto.cpp)
- [Uniform Initialization ](./c++2.0/uniform_initialization.cpp)
- [initializer_list](./c++2.0/initializer.cpp)
- [explicit for ctors taking more than one argument](./c++2.0/explicit.cpp)
- [range-based for statement](./c++2.0/auto.cpp)
```cpp
for(decl:col) {
statement
}
```
- [=default,=delete](./c++2.0/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](./c++2.0/alias.cpp)
- [template_template.cpp](./c++2.0/template_template.cpp)
- [template template parameter](./c++2.0/template_template.cpp)
- [type alias](./c++2.0/type_alias.cpp)
- [noexcept](./c++2.0/noexcept.cpp)
- [override](./c++2.0/override.cpp)
- [final](./c++2.0/final.cpp)
- [decltype](./c++2.0/decltype.cpp)
- [lambda](./c++2.0/lambda.cpp)
- [Rvalue reference](./c++2.0/rvalue.cpp)
- [move aware class](./c++2.0/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](./c++2.0/hash.cpp)
- [tuple](./c++2.0/tuple.cpp)

### 7.工具篇
#### 7.1 [容器快捷输出工具](./tool/output)
对吴老师的代码进行了修改,[点击此处直通代码](./tool/output/output_container.h)
输入:
```cpp
map<int, int> mp{
{1, 1},
{2, 4},
{3, 9}};
cout << mp << endl;
```
输出结果显示:
```cpp
{ 1 => 1, 2 => 4, 3 => 9 }
```
