What are the best practices for using unique pointers in C++?

When using unique pointers in C++, it's important to ensure proper ownership and avoid memory leaks. Always initialize them and use std::make_unique for better safety.

Can you explain why std::make_unique is preferred?

std::make_unique helps prevent memory leaks by ensuring that the unique pointer is properly initialized and managed. It also avoids the overhead of using new directly.

Are there any situations where I shouldn't use unique pointers?

Yes, avoid using unique pointers in scenarios where shared ownership is required. In such cases, consider using std::shared_ptr instead.

What about performance implications of using unique pointers?

Unique pointers are lightweight and have minimal overhead, making them a great choice for performance-sensitive applications.
