C++ function name readability and consistency

Answer: C function names should be readable and consistent to improve code maintainability and understandability. Readability Guidelines: Use descriptive names Avoid gerunds Consistency Guidelines: Use a consistent naming convention Use Pascal or Camel nomenclature

C for function names Readability and Consistency

In C, function names are an important way for programmers to convey intent and make code easy to read. Following readability and consistency principles can significantly improve code maintainability and understandability.

Readability Guidelines

• #Use descriptive names: Function names should clearly indicate what the function does and avoid abbreviations or ambiguity The name. For example:

int calculate_total_cost();

• Avoid using gerunds: Gerunds make function names lengthy and difficult to read. Using verb forms instead is more concise and clear. For example:

void write_file(const std::string& filename); // 避免：writeFile()
int calculate_total_cost(); // 避免：calculateTotalCost()

Consistency Guidelines

• Use a consistent naming convention: For functions of the same type or purpose, A consistent naming convention should be used. This helps to quickly identify and understand the code. For example:

// 用"_t"后缀表示 template 函数
template<typename T> void print_array(const T* array, int size);
template<typename T> void print_list(const std::list<T>& list);

• Use Pascal or Camel nomenclature: For multi-word names, Pascal nomenclature (the first letter of each word is capitalized) or Camel nomenclature should be used method (the first letter of the word is lowercase, and the first letter of the remaining words is capitalized).

Pascal: CalculateTotalCost()
Camel: calculateTotalCost()

Practical Example

Let’s use these guidelines to improve the function names in the following C code:

// 原代码
int calc_cost(int items, double price);
void writeToLog(const std::string& msg);

// 改进后的代码
int calculate_total_cost(int number_of_items, double item_price);
void write_to_log(const std::string& message);

These improvements improve the code The readability and consistency make the function's function clear at a glance.
