Implementation and analysis of strlen source code in musl
Recently, I was studying the pointer part of Chapter 6 of “C and Pointers”. I saw the implementation of the strlen function in Chapter 6.12. I thought that I was looking at the source code of musl recently, so I carefully analyzed the source code of strlen in musl and found that There are some […]
Implementation of string functions
Implementation of string functions One: strlen()—-calculate the string size Write strlen first, because it will be used by several functions later. code show as below: #define _CRT_SECURE_NO_WARNINGS #include<stdio.h> int my_strlen(char* arr) {<!– –> int sum = 0, i = 0; while (*arr != ‘\0’) {<!– –> sum + + ; arr + + ; } […]
6 implementation options for single-machine idempotence
A friend suddenly asked two days ago: What is the simplest solution to prevent repeated submissions in Java? This sentence contains two key messages, first: Prevent duplicate submissions; second: Easiest. So the author asked him, is it a stand-alone environment or a distributed environment? The feedback I got was that it would be simple if […]
Containerized nacos deployment and implementation of service discovery (gradle)
1. How to deploy mysql in a container 2. How to deploy nacos in a container In order not to expose my server address, this article uses localhost instead of the server address. All localhosts should be adjusted to your own server addresses. In order not to expose my server address, this article uses localhost […]
[C++] Date class implementation, OJ issues related to date calculation
Article directory Date design Date calculation related OJ questions HJ73 Calculate date to day conversion KY111 date difference KY222 Print date KY258 date accumulation In software development, dealing with dates is a common task. In order to easily manipulate dates, we can use the C++ programming language to create a simple date class. In this […]
Implementation of interface automation testing framework based on Junit!
Layered automated testing 5 to 10 years ago, the automated testing we came into contact with was more focused on automated testing of the UI layer. Mercury’s WinRunner/QTP was a typical representative of the commercial automated testing products of that era. At that time, everyone simply wanted to use a Automated tools replace human clicks, […]
OneAPI Intel Experimental Matrix Multiplication Implementation
Introduction to OneAPI oneAPI is a cross-platform, open and unified programming model designed to simplify and accelerate heterogeneous computing. It is led by Intel Corporation and supported by a wide range of partners. The goal of oneAPI is to provide a unified programming environment that enables developers to write high-performance applications on different hardware architectures, […]
Source code and analysis of specific implementation of Set interface
The author was asked this question when participating in an interview at a bank. Have you ever understood the implementation principle of HashSet? Since this small point is only used normally, but the source code has never been seen, so I can only be “short of money”. (Take openjdk-19 as an example) Source code First […]
