Shared Pointers vs Unique Pointers

Shared pointers and unique pointers are both fundamental to modern C++ memory management. To determine when to choose one over the other, it’s important to understand their differences.

	Shared Pointers	Unique Pointers
Ownership Model	Allows shared ownership across multiple areas	Enforces unique ownership at a given time
Reference Count	Uses reference count to manage ownership	Does not use reference count
Overhead	Moderate overhead due to reference counting	Minimal overhead as no reference counting is needed
Complexity	Can be harder to manage due to shared ownership and potential circular references	Generally simpler ownership semantics
Use Cases	Use when multiple parts need access to same object with complex lifetime	Use for most dynamic memory scenarios where sharing is not required
