blogs. The chain. h file is as follows: # Ifndef _ CHAIN_H _ # define _ CHAIN_H _/* declare some data types */typedef int datatype; // declare the Data Type typedef unsigned short uint16; typedef unsigned char bool; /* returned results */typedef enum {TRUE, FALSE} bool_val;/* declared linked list node */typedef struct node {datatype data; struct node * next;} Li

wise, tan eldest brother, you are not a person in the fight!The implementation of the linked list in the kernel is located in the Include/linux/list.h file, and the definition of the linked list data structure is simple.+ struct List_head {A struct list_head *next, *prev;23

The concept of LRU linked list in 1.Buffer cache: When Oracle does not search for the desired buffer in the hash chain, the Oracel service process makes an I/O call and reads the corresponding data block to the disk's data file--except for direct path reading, the contents of the data block are copied to the buffer ca

Data Structure and algorithm JavaScript (3) linked listWe can see that the queue and stack in the javascript concept are both a special linear table structure and a simple array-based Sequential storage structure. Because the javascript interpreter directly optimizes arrays, there is no fixed length of arrays in many programming languages (it is difficult to add an array after it is filled up, to add and delete all elements in the array, you must chan

edge linked list and an inbound edge linked list. The same structure is used to create a linked list, which is divided into two parts. One is a data block, it is used to store the basic information of a node, and the other is a p

This article mainly introduces the data structure and algorithm in JavaScript (3): linked list. This article describes the single-chain table and double-chain table, as well as code instances for adding and deleting sections, for more information about the queue and stack in javascript, we can see that the queue and stack are both a special linear table structure and a simple array-based Sequential storage

to convert its address to the linklistnode * type, and then use the next pointer to operate the original struct address. This should be the data encapsulation mentioned by Lao Tang.This involves one thing, that is, when a large struct is forcibly converted to a small structThe nested struct must be placed in front of the large struct.At this time, the address of the first four bytes of the structure that the operation is stuck in is to operate the original structure, that is, the data node we w

Even this linked list class has been used for a long time, and many unreasonable things have been ruled out. Some places do not want to use STL stuff. I feel that I can control and modify something I write, it can also run well, and if you have time, you can practice writing standard C ++ Code, especially if you want to practice templates, encapsulate abstractions, and so on. If you are lucky enough to be u
