What is a queue in C++ STL? A queue is a container adapter in the C++ Standard Template Library (STL) that operates on a First-In-First-Out (FIFO) basis. Elements are inserted at the back (end) and removed from the front. Given below are the operations of the queue: Enqueue:This f...

The only requirement is that it supports the following operations: front() back() push_back() pop_front() Therefore,the standard container class templates deque and list can be used. By default,if no container class is specified for a particularqueueclass,the standard container class template ...
Dequeue and Priority Queue in C - As we know that the queue data structure is First in First Out data structure. The queue has some variations also. These are the Dequeue and the Priority Queue.The Dequeue is basically double ended queue. So there are t
// atomic operations. atomic_ptr_t<T> c; //读写线程共享的指针,指向每一轮刷新的起点(看代码的时候会详细说)。当c为空时,表示读线程睡眠(只会在读线程中被设置为空) // Disable copying of ypipe object. ypipe_t(const ypipe_t &);
between those two operations, it may find the queue non-empty, but without an element assigned. I can't be sure that's what really happening in your case (I don't know the specifics of the implementation that you're using), but it's quite likely to be ...

Basic Operations Some of the basic operations of the circular queue are as follows: Front:Returns the front position in the circular queue. Rear:Returns the rear position in the circular queue. Enqueue:Enqueue (value) is used to insert an element in the circular queue. The element is always...
