STL 标准库 stack 总结 简介 Constructor 常用的成员函数 简介 Stack 是一种容器适配器/配接器(container adaptor), 被设计用来支持 LIFO 的数据结构. deque 是双向开口的数据结构, 因此以 deque 为底部结构封闭其头部开口, 就可以形成 Stack. adaptor 指的是通过修改某种容器的接口, 形成

std::stack<T,Container>::emplace From cppreference.com <cpp |container |stack Pushes a new element on top of the stack. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with exactly the same arguments as...

1)Default constructor. Value-initializes the container. 2)Copy-constructs the underlying containercwith the contents ofcont.This is also the default constructor.(until C++11) 3)Move-constructs the underlying containercwithstd::move(cont).
