C Coding Standards

When reviewing or generating C code, follow these rules:

File Naming

• Source files: snake_case with .c extension (e.g., user_service.c, data_parser.c)
• Header files: snake_case with .h extension (e.g., user_service.h, data_parser.h)
• Keep names short but descriptive (max ~20 characters)

Header Guards

• Format: UPPER_SNAKE_CASE with _H suffix
• Include path in guard: (e.g., PROJECT_MODULE_FILE_H)

#ifndef USER_SERVICE_H
#define USER_SERVICE_H
// content
#endif /* USER_SERVICE_H */
