What are the differences between C++ pointers and smart pointers?

What are the differences between C++ pointers and smart pointers?

C++ pointers are raw memory addresses, while smart pointers manage memory automatically, preventing leaks.

Can you explain how smart pointers work in C++?

Smart pointers, like std::unique_ptr and std::shared_ptr, handle memory management by automatically deleting the object when no longer needed.

When should I use smart pointers instead of raw pointers?

Use smart pointers when you want to ensure automatic memory management and avoid memory leaks, especially in complex applications.

Are there any performance drawbacks to using smart pointers?

Smart pointers can introduce slight overhead due to reference counting, but they greatly enhance safety and maintainability.
