What is automatic memory management in C++?

Automatic memory management in C++ refers to the use of smart pointers and containers that handle memory allocation and deallocation automatically.

Can you explain how smart pointers work?

Sure! Smart pointers, like std::unique_ptr and std::shared_ptr, manage the lifetime of dynamically allocated objects, ensuring they are deleted when no longer needed.

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

The main advantages include automatic memory management, prevention of memory leaks, and safer code through ownership semantics.

Are there any downsides to using smart pointers?

Yes, they can introduce some overhead and complexity, especially with shared ownership, which may lead to circular references if not managed properly.
