typedef Best Practices

Guidelines for effective typedef usage

✅ DO: Use for clarity

typedef float Celsius; // Clear intent and units

⚠️ CAREFUL: Pointer typedefs

typedef int *IntPtr; // Hides pointer nature

❌ DON'T: Overuse for simple types

typedef int integer; // Unnecessary complexity

typedef Design Philosophy

🎯 Semantic Naming

Use typedef to give types meaningful, domain-specific names that express purpose

🔄 Abstraction Layer

Create an abstraction layer that allows easy type changes across your codebase

📚 Readability First

Prioritize code readability and maintainability over brevity

Common Pitfalls

Over-aliasing

Don't typedef every basic type - only when it adds semantic value

Hiding Complexity

Pointer and array typedefs can make code harder to understand

Inconsistent Style

Choose a naming convention (CamelCase, snake_case) and stick to it
