无锁栈(lock-free stack)无锁数据结构意味着线程可以并发地访问数据结构而不出错。例如,一个无锁栈能同时允许一个线程压入数据,另一个线程弹出数据。不仅如此,当调度器中途挂起其中一个访问线程时,其他线程必…

The following example shows the usage of the std::stack::empty() function. At first, we are trying to create a stack s with no elements in it and we verify it using the empty() function. Then, we insert/push element '1' into the stack and use the empty() function to determine ...
std::stack类是一种容器适配器,它给予程序员栈的功能——特别是 FILO(先进后出)数据结构。 该类模板用处为底层容器的包装器——只提供特定函数集合。栈从被称作栈顶的容器尾部推弹元素。 std::stack的全部成员函数均为constexpr:在常量表达式求值中创建并使用std::stack对象是可能的。
