C++ function naming: CamelCase and Underscore naming conventions

C There are two function naming conventions: CamelCase, the first letter of each word is capitalized, excluding the first word. Underscore, words are separated by underscores. CamelCase is compact and easy to read, while Underscore is easier to maintain consistency. It is recommended to use CamelCase for shorter function names and Underscore for longer or confusing function names.

C Function Naming: CamelCase and Underscore Naming Convention

Naming convention is crucial in software development, it can improve the reliability Readability and maintainability. There are two common function naming conventions in C: CamelCase and Underscore.

CamelCase

CamelCase is a style of function naming that capitalizes the first letter of each word, but not the first word. For example:

void calculateArea(double width, double height);

Underscore

The Underscore naming convention uses underscores to separate words. For example:

void calculate_area(double width, double height);

Advantages and Disadvantages

Both conventions have their own advantages and disadvantages.

• CamelCase Advantages: Compact and easy to read, especially when naming shorter functions.
• Underscore Pros: Easier to achieve consistency because it is based entirely on lowercase letters.

Practical case

The following is an example of a class using the CamelCase and Underscore naming conventions:

class Shape {
public:
    void calculateArea(double width, double height);
    double getArea() const;
};

class ShapeManager {
public:
    void addShape(Shape shape);
    void removeShape(Shape shape);
};

Suggestions

For shorter function names, CamelCase is usually more concise and clear. The Underscore naming convention is clearer for longer function names or functions with confusing names.

Here are some suggestions:

• Keep naming conventions consistent.
• Function names should be descriptive so that their functionality is easy to understand.
• Avoid using abbreviations or ambiguous naming.
