How do I use unique pointers in C++ effectively?

How do I use unique pointers in C++ effectively?

Unique pointers are smart pointers that ensure a single ownership of a dynamically allocated object. You can create one using std::unique_ptr<T> ptr = std::make_unique<T>(args);.

What are the advantages of using unique pointers over raw pointers?

Unique pointers automatically manage memory, preventing memory leaks and dangling pointers. They also provide better exception safety.

Can I transfer ownership of a unique pointer?

Yes, you can transfer ownership using std::move(). For example, std::unique_ptr<T> ptr2 = std::move(ptr1);.

Are there any limitations to using unique pointers?

Yes, unique pointers cannot be copied, only moved. This means you cannot have multiple unique pointers pointing to the same object.
