Best practices for naming C++ functions

C Best practices for function naming include: Length and clarity: Keep names short (up to 30 characters) and start with a verb. Specificity and context: Describe exactly what the function does and include a class or module prefix. Consistency and style: Keep your naming style consistent across your codebase and follow language conventions.

Best Practices in C Function Naming

In C code, clear and meaningful function names are important for improving readability, maintainability and Comprehensibility is crucial. Following these best practices can help you write descriptive, easy-to-understand function names.

Length and Clarity

• Keep function names short and concise (usually no more than 30 characters).
• Avoid using abbreviations or unfamiliar acronyms.
• Use a descriptive verb to start the function name.

Specificity and Context

• Use function names to describe exactly what the function does.
• Consider the context in which the function will be used and include it in the name.
• If the function belongs to a specific class or module, include the prefix in the name.

Consistency and style

• Maintain a consistent function naming style throughout the code base.
• For functions with similar functionality, use similar naming conventions.
• Follow the naming convention of the language or framework (e.g. C STL).

Practical Case

Here are some examples of C function naming that follow best practices:

// 计算用户的年龄
int calculate_user_age(const Date& birthdate, const Date& today);

// 添加一个元素到向量
void add_element_to_vector(std::vector<int>& v, int element);

// 获取指定类的实例
MyClass* get_instance(int id);

Following these guidelines can help you write C that is easy to understand and maintain. functions, thereby improving overall code quality.
