Software Engineering--The realization of theory, method and practice

Software Engineering--The realization of theory, method and practice

Software implementation is a key process of a software product from concept to entity, which translates the results of detailed design into program code written in a programming language and can eventually run. Although the quality of the software depends on the software design, the standard program design style will have a noticeable impact on the software maintenance in the later stage. The process of software implementation includes basic activities such as code design, design review, code writing, code walking, code compiling, and unit testing. First, developers need to correctly understand the user requirements and software design model, add some missing detailed design, further design the structure of the program code, and self-check the design results, and secondly, according to the program design results and programming specifications, such as writing code, but before compiling should refer to the code to check the list to complete the Code walk; Compile the code to debug and correct errors, and complete unit testing work.

Programming language has been evolving and evolving, and its development has undergone a process from machine language to high-level language. The program designer should choose according to the requirements.

In the early days of computer development, it was thought that programs were provided to machines rather than read by people. Therefore, it is sufficient to implement the correct logic so that the computer executes, and whether it is irrelevant to use a unified programming specification. As the scale of software systems grows, it is difficult to read the code in the course of testing and maintenance. Today, people no longer over-emphasize the skill of programming, but use code readability as an important factor affecting software quality.

The programming style affects the readability and testability of the program to a great extent, and even affects the execution efficiency of the program.

Finally, don't forget to review the software code
