What are the naming rules for structures in C language?

Structural naming specifications in C language: Use camel nomenclature or underscore nomenclature to avoid mixed use. The name clearly expresses the purpose of the structure. The naming of related structures reflects correlation. Be careful to be verbose in nested structures, using abbreviations or concise words. Keep naming style consistent in large projects and use the code style checking tool.

In C language, structure naming? This question seems simple, but in fact there are many tricks. Do you think it's enough to just name it? Too young, too simple! A good naming style is related to the readability, maintainability of the code, and even the success or failure of the entire project. After reading this article, you can understand why old birds are so serious about naming.

Let’s talk about the most basic thing first. C language itself does not have any particularly strict regulations on structure naming, and it does not have mandatory naming specifications like some languages. But we programmers are not savages, we have to be a little bit of a rule. Generally speaking, it is good to use CamelCase or underscore nomenclature (snake_case). Camel method, lowercase first letter, uppercase first letter of subsequent words, such as studentInfo ; underscore method, words are connected by underscore, such as student_info . Which one to choose depends mainly on team habits and project style. Don't use it in a mess, it's a disaster!

Let’s talk about some advanced ones. The name should clearly express the purpose of the structure. struct student is much better than struct s , isn't it? struct student can tell at a glance that it is a structure about student information, and struct s ? Guess you to death! Therefore, the naming should be accurate and concise to avoid ambiguity. Don't sacrifice the readability of the code in order to save a few characters. I have seen many projects, and the structure names are so messy that it is very hard to change.

There are some tips. If you define a set of related structures, consider embodying this relationship in the name. For example, struct address and struct contact are both related to personal information, and the name can reflect this connection. This helps to understand the overall structure of the code.

Let’s talk about potential pitfalls. When nesting structures, you need to be even more careful when naming them. If there are too many nested layers, the name can easily become lengthy. At this time, you need to design the name well to avoid confusion. For example, you can use abbreviation or more concise words instead of lengthy descriptions. But remember, simplicity does not mean obscure!

Finally, I want to share a experience of my own. In large projects, using a consistent naming style is crucial. This requires team members to follow together and use some code style checking tools to ensure code consistency. This can greatly improve teamwork efficiency and avoid code confusion caused by inconsistent naming styles. This is a valuable experience I have summarized in my many years of programming career!

Here is a simple example showing the structure definitions of different naming styles:

 <code class="c">// 驼峰命名法struct studentInfo { char name[50]; int age; char address[100]; }; // 下划线命名法struct student_info { char name[50]; int age; char address[100]; };</code>

Remember, naming is an art and a science. A good naming style can make your code more elegant, easier to understand and maintain. On the contrary, bad naming style will put you and your team in endless pain. So, please pay attention to naming!
