Net-tools, linuxnettools I. Introduction Net-tools contains the following programs, which constitute the basis of the Linux network. Arp is used to operate on the high-speed cache of the core ARP (Address Resolution Protocol). It is usually used to add or delete an entry and dump the ARP high-speed cache. Dnsdomainname displays the system's DNS domain name. Domainname indicates the system's NIS/YP domain name. Hostname is used to set or display the

A short time ago on the internet to see a fast fuzzy algorithm, performance is very good.SOURCE Blog:Http://www.lellansin.com/super-fast-blur-%E6%A8%A1%E7%B3%8A%E7%AE%97%E6%B3%95.htmlBloggers have made simple bug fixes and performance optimizations.This algorithm is used to blur a 5000x3000 image on the host son, which takes only 500-600 milliseconds and is very fast.The code is as follows:/** Super Fast Blur v1.1+* Original Author:mario Klingemann (c + + version) * Original Address:http://incub

This is a long time to learn C did a practice exercise, the topic of the request is probably the user input three-digit reverse output, such as user input 123, and then the program should output the result is 321. If you encounter user input 100, then the program should output 1. And then I'm going to extend this program to accommodate three-digit or three-digit numbers or less.So in this problem, my first idea is to find a way to take the user input of the number to open him, and then put in th
