比较两个容器适配器底层容器的内容。比较是通过将相应的运算符应用于底层容器来完成的。

成员函数
stack::stack
stack::~stack
stack::operator=
元素访问
stack::top
容量
stack::empty
stack::size
修改器
stack::push
stack::push_range (C++23)
stack::emplace (C++11)
stack::pop
stack::swap (C++11)
非成员函数
swap(std::stack) (C++11)
operator==operator!=operator<operator>operator<=operator>=operator<=> (C++20)
辅助类

lhs, rhs	-	要比较其内容的容器适配器
- `T` 必须满足 EqualityComparable 的要求。
