I/O Best Practices & Tips
📤 Output Tips

Use std::cout << for output. Chain multiple values with additional << operators.

📥 Input Guidelines

Always prompt users before input. Use std::cin >> to read values into variables.

🎨 Formatting

Use '\n' instead of std::endl for better performance. std::endl flushes the buffer.

🔗 Chaining

You can chain I/O operations: std::cout << "Result: " << value << '\n';
