<set> std::set::upper_bound C++98 C++11 iterator upper_bound (const value_type& val) const; Return iterator to upper bound Returns an iterator pointing to the first element in the container which is considered to go afterval. The function uses its internalcomparison object(key_comp) to de...

Because some existing code depends on the value of the macro__cplusplusbeing199711L, the MSVC compiler doesn't change the value of this macro unless you explicitly opt in by setting/Zc:__cplusplus. Specify/Zc:__cplusplusand the/stdoption to set__cplusplusto the appropriate value. ...
In a set, the value of an element also identifies it (the value is itself the key, of type T), and each value must be unique. The value of the elements in a set cannot be modified once in the container (the elements are always const), but they can be inserted or removed from th...
Unordered Set/Multiset Unordered map/Multimap 二、各个容器的底层结构(源码分析) 1、list容器 主要看这里的__list_node的结构和list——iterator的结构,右上角的代码框可以看到链表中的结点的结构为一个pre指针和一个next指针以及一个数据域,这也是我们熟知的双向链表的结构,这里补充一点容器都是前闭后开区间,所...
std::tie(iter, inserted) = set_of_s.insert(value); if (inserted) std::cout << "Value was inserted successfully\n"; } 结果如下: Value was inserted successfully std::tie会将变量的引用整合成一个tuple,从而实现批量赋值。 int i; double d; string s; ...
默认构造函数,创建一个空的 std::thread 执行对象。 初始化构造函数,创建一个 std::thread 对象,该 std::thread 对象可被 joinable,新产生的线程会调用 fn 函数,该函数的参数由 args 给出。 拷贝构造函数(被禁用),意味着 std::thread 对象不可拷贝构造。 Move 构造函数,move 构造函数(move 语义是 C++11 ...
