Programming is the process of giving a program to solve a specific problem and is an important part of software construction activities. Programming often uses a certain programming language as a tool to give programs in this language. The programming process should include different stages such as analysis, design, coding, testing, and debugging. Professional programmers are often called programmers.
#Any design activity seeks a balance between various constraints and conflicting requirements, and programming is no exception. In the early days of the development of computer technology, because machine resources were relatively expensive, the time and space cost of the program were often the main factors of design concern; with the rapid development of hardware technology and the increasing scale of software, the structure, maintainability, and complexity of the program Factors such as usability and scalability are increasingly important.

In a sense, the emergence of programming even precedes the emergence of electronic computers. Ada Lovelace, the daughter of the famous British poet Byron, designed a program for calculating Bernoulli numbers on Babbage's Analytical Engine. She even created the concepts of loops and subroutines. Due to her pioneering work in programming, Ada Lovelace has been called the world's first programmer. [1]

On the other hand, in the early days of the development of computer technology, software construction activities were mainly programming activities. However, with the development of software technology, software systems have become more and more complex, and many specialized software systems have gradually evolved, such as operating systems, database systems, and application servers. These specialized software systems have increasingly become part of the general computing environment. . In this case, the content of software construction activities is becoming more and more abundant, no longer just pure programming, but also including database design, user interface design, interface design, communication protocol design and complex system configuration process.
General process
Analysis of the problem
Carefully analyze the accepted tasks and study the given conditions , analyze the final goals that should be achieved, find out the rules for solving problems, choose problem-solving methods, and complete practical problems.
Design algorithm
That is to design the method and specific steps to solve the problem.
Write a program
Translate the algorithm into a computer programming language, and edit, compile and connect the source program.
Run the program and analyze the results
Run the executable program and get the results. Being able to get running results does not mean that the program is correct. The results must be analyzed to see if they are reasonable. It is unreasonable to debug the program, that is, the process of discovering and eliminating faults in the program through computer testing.
Writing program documentation
Many programs are provided for others to use. Just like formal products should provide product manuals, programs officially provided to users must be provided with User provides program instructions. The content should include: program name, program functions, operating environment, program loading and startup, data that needs to be input, and usage precautions, etc.
