What is the difference between shared_ptr and unique_ptr in C++?

What is the difference between shared_ptr and unique_ptr in C++?

In C++, both shared_ptr and unique_ptr are smart pointers used for memory management, but they have different ownership models.

Can you explain how shared_ptr manages memory differently?

Sure! shared_ptr allows multiple pointers to own the same resource, using reference counting to manage the resource's lifetime.

And what about unique_ptr? How does it work?

unique_ptr, on the other hand, ensures that only one unique_ptr can own a resource at a time, preventing shared ownership.

When should I use one over the other?

Use unique_ptr when you want sole ownership and shared_ptr when you need shared ownership among multiple pointers.
