PascalCase and SnakeCase naming conventions in function naming

The function naming conventions are PascalCase and SnakeCase. PascalCase capitalizes the first letter of a word, SnakeCase connects words with underscores and lowercases them. PascalCase improves readability, SnakeCase improves consistency, and both improve maintainability.

PascalCase and SnakeCase naming convention in function naming

In programming, function naming follows a specific naming convention to ensure Code readability, consistency and maintainability. Two common function naming conventions are PascalCase and SnakeCase.

PascalCase

The PascalCase naming convention capitalizes all words, including the first letter:

calculateAverage()

SnakeCase

SnakeCase Naming Convention Connect all words with underscores and all lowercase:

calculate_average()

Advantages of Choosing a Naming Convention

• Yes Readability: PascalCase is easier to read because it separates words.
• Consistency: SnakeCase is more consistent because it forces underscores to connect words.
• Maintainability: As your code base grows, consistent naming conventions improve maintainability and scalability.

Practical case

The following is an example of a function using the PascalCase naming convention:

double calculateAverage(vector<double>& numbers) {
    double sum = 0.0;
    for (double number : numbers) {
        sum += number;
    }
    return sum / numbers.size();
}

The following is a function using the SnakeCase naming convention Example:

def calculate_average(numbers):
    sum = 0.0
    for number in numbers:
        sum += number
    return sum / len(numbers)
