What are the benefits of using smart pointers in C++?

Smart pointers in C++ help manage memory automatically, reducing the risk of memory leaks and dangling pointers.

Can you explain how they differ from regular pointers?

Unlike regular pointers, smart pointers automatically handle memory deallocation when they go out of scope, ensuring safer memory management.

What types of smart pointers are there?

There are three main types: std::unique_ptr, std::shared_ptr, and std::weak_ptr, each serving different use cases.

Are there any performance drawbacks to using smart pointers?

While smart pointers add some overhead, they often improve overall performance by preventing memory leaks and improving code safety.

When should I use smart pointers instead of raw pointers?

Use smart pointers when you need automatic memory management, especially in complex applications where ownership semantics are important.
