Variadic Templates

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
}

=default,=delete

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.

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

tuple
