This article mainly explains "how programmers write high-quality code programs". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how programmers write high-quality code programs.

The naming of each variable is carefully considered.

The average programmer's variable naming is so casual that it will come out when you go to abcd, while the naming of high-quality code is very standard, neither long nor short, so that you can read out their meaning without being verbose. In short, you can tell whether a program is elegant from variable naming.

Read variables from the configuration file

Many people like to modify the value of a variable through comments in a program, which is very wrong. First of all, it is not elegant to modify the value of a variable by modifying the code, not to mention that useless comments affect the cleanliness of the code.

A good program must read the required variables from the configuration file, and it is much more convenient for a person to modify the configuration file than to change the value in the source code.

Your program is excellent when you learn to read and modify the configuration from the configuration file.

There must be test code.

A high-quality program must have test code, remember that no matter how simple the program function, we have to write test code. Why TDD is popular, because many people don't bother to write code, while TDD forces you to write test code because it makes the code more robust, while others can modify the code without having a more significant impact.

We do not necessarily use TDD for program development, but we must write test code, with test code, your program can withstand trouble, remember, sometimes you will get confused, but the test code will not, the code that runs through the test case can at least reduce a lot of errors.

Be sure to keep a journal

After a program is developed, you have no way to predict its environment and how it will be used. all you can do is log when it goes wrong, so that you can analyze it. At the same time, in the process of program development, logging can also facilitate us to debug the code, and logging is also a way of debugging analysis.

Never rewrite the code

When you write repetitive code in many places, you should remember to ReFactor them, never write repetitive code, and when you find repetition, remember to use functions to abstract it.

Many people like to copy the code, and then you will find that a lot of the code in his program is the same, and when he wants to modify the code, he has to change everything, which is not only a waste of time, but also may cause code omissions.

The code format should be unified

I remember hearing a joke before that we Chinese wrote the code as if it were written by a thousand people, while the code written by an Indian was written by a thousand people.

We don't require everyone to write the same style of code, but we need you to write consistent code and follow the code recommendations.

Now all languages have their own code format style, you just have to write according to the rules.

At this point, I believe you have a deeper understanding of "how programmers write high-quality code programs". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
