Web用法 圆形缓冲区的一个有用特性是：当一个数据元素被用掉后，其余数据元素不需要移动其存储位置。相反，一个非圆形缓冲区（例如一个普通的队列）在用掉一个数据元素后，其余数据元素需要向前搬移。换句话说，圆形缓冲区适合实现先进先出缓冲区，而非圆形缓冲区适合后进先出缓冲区。 Web线程池的线程个数固定。 线程执行流程 执行任务 start启动numThreads个数量的线程，并且创建的同时，执行runThreads函数，runThreads内部是通过take()来获取任务，如果此时任务队列为空，就会一直wait，等待任务的到来。; 添加任务 run函数作用是将任务添加到队列中，然后notify通知线程来执行任务。

WebThe circular_buffer has a capacity of three int. Therefore, the size of the buffer will never exceed three. The std:: accumulate algorithm evaluates the sum of the stored elements. The semantics of the circular_buffer can be inferred from the assertions. You can see the full example code at circular_buffer_sum_example.cpp.
