C++11新特性¶
-
Spaces in Template Expressions
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
- Automatic Type Deduction with auto
- Uniform Initialization
- initializer_list
- explicit for ctors taking more than one argument
- range-based for statement
for(decl:col) {
statement
}
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)

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
