大std::stack类是一个容器适配器，它为程序员提供了堆栈的功能--具体来说，是一个filo%281先进，最后输出%29数据结构。
类模板充当底层容器的包装器--只提供一组特定的函数。堆栈从底层容器的后面推入并弹出元素，称为堆栈顶部。
模板参数
T | - | The type of the stored elements. The behavior is undefined if T is not the same type as Container::value_type. (since C++17) |
|---|---|---|
Container | - | The type of the underlying container to use to store the elements. The container must satisfy the requirements of SequenceContainer. Additionally, it must provide the following functions with the usual semantics: back() push_back() pop_back() The standard containers std::vector, std::deque and std::list satisfy these requirements. |
back()
push_back()
pop_back()
标准容器std::vector，，，std::deque和std::list满足这些要求。
