- 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
-
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 -
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
