How to apply the camel nomenclature in C language?

Camel nomenclature is usually not used in C language, but for the sake of readability, camel nomenclature or underscore separation nomenclature can be used: Camel nomenclature: the first letter of a word is capitalized, connected together, such as userName and studentAge. Underline separation method: Words are separated by underlines, such as user_name and student_age.

How to apply the camel nomenclature in C language?

You ask how to use the nomenclature of camel in C language? This question is well asked because it has a little philosophical meaning in itself. In C language, this old guy has a concise and direct heart, which is completely different from the fancy style of Java or C#. It is not that strict with naming norms, and it can even be said to be more "casual". Therefore, whether to use the camel nomenclature is more of a style choice than a mandatory requirement.

To put it bluntly, the C language compiler doesn't care about what naming style you use, it only cares whether the syntax of your code is correct. But we programmers have to pay attention to the code. The code is written for people to read, and it is even more convenient for future maintenance. Therefore, even if there are no hard regulations in C language, we should follow some conventional norms to make the code easier to read and understand.

So how does the nomenclature of camel be reflected in C language? In fact, it is very simple, it is to capitalize the first letter of the word and connect it. For example, userName , studentAge , calculateSum , etc. This is no different from the nomenclature of camels you see in other languages.

However, in C language, you will find that many people prefer to use underscores to separate words, such as user_name , student_age , calculate_sum . This is because of the tradition of C language and a deeply rooted habit of many C programmers. These two styles have their own advantages and disadvantages:

The nomenclature of camel looks simpler and more in line with the trend of modern programming languages, especially in the environment of C or hybrid programming, which can maintain the consistency of code style. But for some old-school C programmers, it may feel that it is a bit "unparalleled".

The underscore separation method is more in line with the traditional style of C language, looks more "original" and is more easily accepted by older generation C programmers. However, underscores can make the code look a bit verbose in the case of long variable names.

So, how should I choose? It depends on your team specifications and personal preferences. There is no absolute correct answer. It is important to keep the code style consistent. In a project, it is best not to mix these two styles. If you work on a team, you should follow the team's code specifications; if you develop alone, choose a style that you think is more comfortable and stick to it.

Finally, I will show you an example to appreciate the difference between the two styles:

 <code class="c">// 驼峰命名法int calculateAverageScore(int scores[], int count) { int sum = 0; for (int i = 0; i </code>

You see, the functions are exactly the same, but the naming style is different. Which one to choose is entirely up to you. Remember, it is the readability and maintainability of the code, as well as the specifications of the team. Don’t worry about your style, it’s the right way to focus on writing high-quality code.
