What are the benefits of using std::unique_ptr in C++?

Using std::unique_ptr helps manage memory automatically, preventing memory leaks and ensuring proper resource management.

Can you explain how it differs from raw pointers?

Unlike raw pointers, std::unique_ptr cannot be copied, only moved, which enforces ownership semantics and prevents dangling pointers.

Are there any performance implications?

Generally, std::unique_ptr has minimal overhead compared to raw pointers, and it can improve performance by reducing memory management errors.

When should I prefer std::unique_ptr over std::shared_ptr?

Use std::unique_ptr when you want sole ownership of a resource, and std::shared_ptr when you need shared ownership among multiple owners.

Can you give an example of using std::unique_ptr?

Sure! Here's a simple example:

std::unique_ptr<int> ptr = std::make_unique<int>(10);
