CamelCase nomenclature for C++ function naming

C Function naming uses camel case naming, which helps to improve code readability. The specific rules are as follows: the first letter is lowercase and the first letter of subsequent words is capitalized (Pascal nomenclature)

CamelCase naming in C function naming: improve code readability

In C, it is a best practice to use camelCase naming for functions. Helps improve code readability and maintainability. The basic rules of this naming method are as follows:

• The first letter is lowercase: The first letter of the function name should be lowercase.
• The first letter of subsequent words should be capitalized: The first letter of subsequent words in the function name should be capitalized, which is called Pascal nomenclature.

For example, a function that calculates area can be named calculateArea():

double calculateArea(double length, double width);

Practical case

Consider a function that counts the number of occurrences of a character in a given string:

Wrong naming:

int count_characters(string data);

This naming is difficult to read because there is no space between the words Clear boundaries.

The correct way to use camel case naming:

int countCharacters(string data);

This naming method is clearer and easier to read because words are distinguished by camel case.

Other Notes

• Avoid using abbreviations.
• Keep function names concise and clear.
• For private or protected functions, you can add an underscore at the beginning of the name. For example: _calculateArea().

Using camel case naming can greatly improve the readability and maintainability of C code. By following these best practices, you can write code that is easier to read, understand, and maintain.
