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

When using unique pointers in C++, it's important to ensure proper ownership semantics. Always initialize them with std::make_unique when possible, and avoid using raw pointers.

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 manages the memory allocation, making your code safer and cleaner.

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 compared to raw pointers. They are generally efficient, but be mindful of the cost of moving them around.
