Int a [5] = {1, 2, 3, 4, 5}; printf ("% d \ n", * (int *) ( a + 1)-2 );, printf % d What is the result of a certain convincing pen question in a certain year? The answer is 4. Why? My understanding (do not know if it is correct ): A is an array pointer of the int type [5], so a plus 1 is actually a + sizeof (int)

Scenario: Resolve a lookup in a large amount of data on the hard disk. Because a large amount of data is stored in the hard disk, can not be loaded into memory all at once, and each time a data read the hard disk, reading speed is too slow, it is necessary to use a part of a data structure read in, this is the role of multi-path search tree. 2-3 Trees 2 nodes: Each of the points contains one element and tw

to return for a second time, and then an exception will occur. To resolve this situation, we can lock the interface when there is a network request and not allow the user to do more (the better way is to just lock some buttons rather than the entire interface.) But here's an example of locking the entire interface. Our solution is simple: When Qnetworkaccessmanager makes a request, we enter a new event loop that blocks the operation. Our code example is as follows: 1

Tags: code image send delay bandwidth technology pre class sendWithout assembly, the number of threads is simplified to a direct while loop recv, setsockopt so_sndbuf, So_rcvbuf set to 256*1024, the test result in a short time is 6.7gb/s. But the long test results are as follows: The horizontal axis of the ROS receives the number of event, in 40000 units. (x, Y) indicates that when Ros receives the x*40000 event, the bandwidth of the receiving end is Y gbits/s. Event size is 2KB. As can be seen

From the previous introduction, we know that in a binary tree, each node has only one data item, with a maximum of two child nodes. If you allow each node to have more data items and more child nodes, it is a multi-fork tree. This blog we will introduce the--2-3-4 tree, which is a multi-fork tree, with a maximum of four child nodes and three data items per node.1, 2
