How to apply snake nomenclature in C language?

In C language, snake nomenclature is a coding style convention, which uses underscores to connect multiple words to form variable names or function names to enhance readability. Although it won't affect compilation and operation, lengthy naming, IDE support issues, and historical baggage need to be considered.

Snake-shaped nomenclature? In C? This question is awesome! The C language itself does not have a built-in mechanism to enforce any specific naming convention, and does not have strict code style checks like some modern languages. Therefore, "applying" the snake nomenclature is more of a coding style convention, a norm that is consciously abide by in order to improve the readability and maintainability of the code.

To put it bluntly, it means that when you write C code, you decide whether to use this style. It itself will not affect the compilation and operation of the program, but it will affect the degree of understanding of the code by the programmer working with you (or you in the future).

Snake nomenclature, as the name implies, is to use underscores to connect multiple words to form a variable name or function name. For example: my_variable , calculate_average , user_input_length . This is in contrast to the camel nomenclature ( myVariable , calculateAverage ) in C or Python.

So, what are the benefits of using snake nomenclature in C?

The benefits are obvious: Enhanced readability. A long variable name can clearly express its meaning if it is divided into multiple words with an underscore, avoiding puzzling abbreviations and incomprehensible naming. Just imagine, which one is easier to understand, usr_inp_len or user_input_length ? The answer is self-evident.

However, there are also some potential "pits".

First, lengthy. Serpentine nomenclature often produces longer variable names, which may make your code look a bit bloated, especially in some scenarios where variable names themselves are relatively long. This requires you to weigh the pros and cons and find a balance between readability and simplicity.

Second, IDE support. Although not a big problem, some IDEs may not be as friendly to the automatic completion function of serpentine nomenclature as the camel nomenclature. This is just a small detail, but it is also a factor that needs to be considered for programmers who are efficient first.

Third, historical burden. Many old C code bases may not follow the serpentine nomenclature. If you maintain both old and new codes in a project, inconsistencies in style may cause some trouble.

Finally, I will show you an example to experience the application of snake nomenclature in C language:

 <code class="c">#include <stdio.h> int calculate_average(int numbers[], int count) { int sum = 0; for (int i = 0; i </stdio.h></code>

This example shows how to use serpentine nomenclature to name variables and functions. Note that this is just a style choice, and the compiler will not report an error because you use the snake nomenclature. The key is to maintain the consistent naming style within the project in order to improve the maintainability of the code. Remember, the code is written for people to see, and the second is executed for machines. The most important thing is to choose a naming style that suits your project and team.
