As an expert in the field of programming education, Zhao Jiangyu has rich teaching experience and profound programming skills. 2. Zhao Jiangyu's programming course enjoys a good reputation among students and has made remarkable achievements.
Programming is the process of making computer code solve a certain problem, specifying a certain operation mode for a certain computing system, making the computing system run according to this calculation mode, and finally getting the corresponding results.
In order to make the computer understand people's intentions, human beings must tell the computer the ideas, methods and means of the problems to be solved in a form that the computer can understand, so that the computer can work step by step according to people's instructions and complete a certain task. This communication process between people and computing systems is programming.
Programming is the Chinese abbreviation of programming, which is the process of making computer code solve a certain problem, specifying a certain operation mode for a computing system, making the computing system run according to this calculation mode, and finally getting the corresponding results. Programming is a "controllable system" with logic flow function. Programming is not necessarily aimed at computer programs, but it can be regarded as programming for systems with logical computing ability.
The implementation principle of programming.
Computers cannot directly identify, understand and execute source programs other than machine language, and all of them must be converted into directly executable programs by computers in some way. There are two ways to convert a source program written in a high-level programming language into a machine object program: interpretation and compilation. In the interpretation mode, the computer interprets and executes the source program written in a high-level language, and cannot form the target file and the execution file.
In the compiling mode, the source program is processed by a compiler corresponding to the programming language used, and the processed source program is converted into a target program represented by binary code through lexical analysis, syntax analysis, semantic analysis, code generation and code optimization, and the function calls and system function calls used in the program are embedded into the target program through linked program processing to form a binary executable file that can be continuously executed.
