What are some use cases for shared_ptr in C++?

What are some use cases for shared_ptr in C++?

shared_ptr is useful for managing dynamic memory in C++. It allows multiple pointers to share ownership of an object.

Can you give me an example of when to use shared_ptr?

Sure! It's great for situations where you have multiple objects needing access to a single resource, like in a graph structure.

Are there any performance considerations I should be aware of?

Yes, shared_ptr has some overhead due to reference counting, so it may not be ideal for performance-critical applications.

What about using shared_ptr with custom deleters?

Using custom deleters with shared_ptr can help manage resources that require specific cleanup, like file handles or network connections.
