How do smart pointers help prevent memory leaks in C++?

Smart pointers in C++ automatically manage memory by ensuring that objects are deleted when they are no longer needed.

Can you explain the different types of smart pointers?

Sure! The main types are std::unique_ptr, std::shared_ptr, and std::weak_ptr. Each has its own use case.

What is the difference between shared_ptr and unique_ptr?

unique_ptr allows only one owner of the resource, while shared_ptr allows multiple owners, managing reference counts.

Are there any downsides to using smart pointers?

Yes, while they help prevent memory leaks, they can introduce overhead and complexity, especially with circular references.
