C++ function best practices: How to define meaningful function names?

In order to ensure the readability and maintainability of C code, it is important to define meaningful function names. Specific guidelines include: Use verbs and nouns to describe function purpose, such as "GetAverage" or "UpdateUserInfo". Keep names short but descriptive and avoid long or ambiguous names. Use camelCase nomenclature, using capital letters to indicate word boundaries. Avoid abbreviations or technical terms, keep naming consistent, and isolate function names to prevent conflicts.

C function best practice: Define meaningful function names

In C, a function name identifies the function and serves as The key parts it references in the code. Defining meaningful function names is critical to ensuring code readability, maintainability, and scalability.

Guidelines:

• Use verbs and nouns to describe function purpose: For example, "GetAverage" or "UpdateUserInfo".
• Keep names short but descriptive: Avoid using lengthy or ambiguous names.
• Use camelCase nomenclature: Connect words together, using capital letters to indicate word boundaries.
• Avoid using abbreviations or technical terms: They can be difficult to understand, especially for newcomers.
• Keep naming consistent: Use functions with similar purposes or functionality using similar naming conventions.

Practical example:

// 定义一个函数来获取数组中的平均值
double GetAverage(const int* arr, size_t size) {
  // ... 你的代码 ...
}

// 定义一个函数来更新用户的信息
void UpdateUserInfo(User& user, const string& name, const string& email) {
  // ... 你的代码 ...
}

These function names clearly describe their function, use verbs and nouns, keep it short and descriptive, and follow camel case formula nomenclature.

Extra Tip:

• Use namespaces to isolate function names: In large projects, namespaces prevent function name conflicts.
• Avoid using special characters: They may cause syntax errors or be incompatible with the compiler.
• Use conventions in function names: For example, a prefix or suffix to indicate the function type.
• Review and update function names: Over time, when the function's functionality changes, the function name should also be updated.
