template <typename T> typename LockFreeStack<T>::HazardPointer LockFreeStack<T>::hazard_pointers_[kMaxHazardPointerNum]; 是定义静态成员数组hazard_pointers_[kMaxHazardPointerNum],也就是我们通常所说的静态成员数组初始化。语法相当丑陋,但是只能这么写。使用风险指针的方法实现内存回收虽然很简单,也的确安全地...

Now, therefore, we land in a situation of using queue and now we will go through the proper working: For implementing queue, we need to get two pointers which will continuously keep a track on both the ends and will get incremented when we need to enqueue an element from the front and...

In a circular queue, there are two pointers, front and rear. You can dequeue elements using the front pointer and enqueue elements using the rear pointer in a circular queue.See the following Example:# Import deque from collections module from collections import deque # Create a deque with ...
you open the file, seek a particular location, and read from or write to that file. RandomAccessFiles can be seen as "large" C-type byte arrays that you can access at any random index "directly" using pointers. File portions can be used as ByteBuffers if the portion is mapped into ...
