- const README: rewrite the space-saving claim per issue #5 follow-ups (constant-expression const vs #define immediates; which const qualify as constant expressions) - const README: fix the class-section diagnosis per issue #338 (overload resolution picks the const overload; the restriction only surfaces once that overload is removed) - sizeof README: virtual-inheritance result is compiler-dependent (GCC merges vbptr+vfptr -> 16, MSVC keeps them separate -> 32) #246 - static README: new section on internal linkage / access restriction with anonymous-namespace comparison #142 - 10-day practice: full problem list table + fixed day links #136 - new design_pattern/singleton/singleton_default.hpp: reusable thread-safe CRTP singleton template, compile+concurrency tested #303

# C++11 新特性概览
|
||
|
||
## 1.C++11新特性
|
||
|
||
- [Variadic Templates](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/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](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/nullptr.cpp)
|
||
|
||
- [Automatic Type Deduction with auto](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/auto.cpp)
|
||
|
||
- [Uniform Initialization ](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/uniform_initialization.cpp)
|
||
|
||
- [initializer_list](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/initializer.cpp)
|
||
|
||
- [explicit for ctors taking more than one argument](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/explicit.cpp)
|
||
|
||
- [range-based for statement](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/auto.cpp)
|
||
|
||
```cpp
|
||
for(decl:col) {
|
||
statement
|
||
}
|
||
```
|
||
|
||
- [=default,=delete](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/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](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/alias.cpp)
|
||
- [template_template.cpp](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/template_template.cpp)
|
||
|
||
- [template template parameter](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/template_template.cpp)
|
||
|
||
- [type alias](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/type_alias.cpp)
|
||
|
||
- [noexcept](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/noexcept.cpp)
|
||
|
||
- [override](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/override.cpp)
|
||
|
||
- [final](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/final.cpp)
|
||
|
||
- [decltype](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/decltype.cpp)
|
||
|
||
- [lambda](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/lambda.cpp)
|
||
|
||
- [Rvalue reference](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/rvalue.cpp)
|
||
|
||
- [move aware class](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/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](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/hash.cpp)
|
||
|
||
- [tuple](https://github.com/Light-City/CPlusPlusThings/tree/master/cpp2.0/cpp11/tuple.cpp)
