iOS multi-threaded programming is always difficult for iOS development beginners to understand and master. Now I will use several examples to gain a more systematic and comprehensive understanding of iOS multi-threaded programming. I hope it will be helpful to everyone. Some programs are a straight line from the starting point to the end; some programs are a circle that keeps looping until it is cut off. A straight line is like a simple Hello World. After running and printing, its life cycle is over, like a flash in the pan; a round one is like an operating system, which keeps running until you shut down. A running program is a process or a task, a process

Shell itself is a program written in C language, which is a bridge for users to use Linux. Shell is both a command language and a programming language. As a command language, it interactively interprets and executes commands entered by the user; as a programming language, it defines various variables and parameters, and provides many control structures found only in high-level languages, including loops and branches. Although it is not part of the Linux system core, it calls most of the functions of the system core to execute programs, create files, and coordinate the running of various programs in a parallel manner. Therefore, for

Hive can control permissions through metadata from version 0.10 (including version 0.10) onwards. In versions before Hive-0.10, permissions are mainly controlled through Linux users and user groups. CREATE, SELECT, and DROP of Hive tables cannot be controlled. Of course, Hive's control of permissions based on metadata is not completely safe. The purpose is to prevent users from accidentally doing operations they shouldn't do. Interested friends can come and take a look

This document mainly talks about the syntax of the fortran language; FORTRAN is the earliest high-level programming language in the world and the most commonly used programming language in the engineering community. It is used in scientific computing (such as aerospace, geological exploration, weather forecasting, construction engineering and other fields ) plays an extremely important role. After more than 40 years of development, with the updates of multiple versions of the FORTRAN language and the emergence of corresponding development systems, its functions have been continuously improved. The latest version of the development system has almost all the features of VC and VB, such as graphical interface programming, databases, etc. I hope this document will help friends in need
