What are some use cases for shared pointers in C++?

Shared pointers in C++ are used for automatic memory management, especially in scenarios where multiple owners are needed.

Can you give me an example of when to use a shared pointer?

Sure! A common use case is in a graph structure where multiple nodes need to share ownership of a child node.

Are there any performance considerations I should be aware of?

Yes, shared pointers have some overhead due to reference counting, so they may not be ideal for performance-critical applications.

What about using shared pointers in multithreading?

In multithreading, shared pointers can be safely used, but you should ensure proper synchronization to avoid data races.
