Naming Conventions

Consistent naming makes code readable and maintainable.

C++ Naming Conventions

PascalCase: StudentBankAccount, calculateArea

Use for: classes, structs, enums, functions, namespaces

camelCase: studentCount, calculateTotal

Use for: variables, functions, parameters

UPPER_SNAKE_CASE: MAX_SIZE, PI, DEFAULT_TIMEOUT

Use for: constants, macros

snake_case: student_bank_account, calculate_area

Use for: variables, functions (alternative style)

Hungarian Notation: iCount, szName, pPointer

Examples

class StudentManager {           // PascalCase
    int studentCount;             // camelCase
    const int MAX_STUDENTS = 30;  // UPPER_SNAKE_CASE

    void calculateAverage() {     // camelCase
        double total = 0;          // camelCase
        for (int i = 0; i < studentCount; i++) {  // camelCase
            total += students[i].gpa;
        }
    }
};

Naming Tips

• Be descriptive: studentCount (not sc)
• Use nouns for variables: student, score, index
• Use verbs for functions: calculate, print, validate
• Avoid abbreviations: count (not cnt)
• Be consistent across your project

File Naming

• PascalCase for classes: StudentManager.cpp
• snake_case for utilities: string_utils.cpp
• Match header and source files
