What are some common mistakes when using smart pointers in C++?

What are some common mistakes when using smart pointers in C++?

Some common mistakes include not using smart pointers when needed, using raw pointers instead, and creating circular references.

Can you explain what circular references are?

Circular references occur when two or more smart pointers reference each other, preventing them from being deallocated.

How can I avoid circular references?

You can avoid circular references by using weak pointers for one of the references in the cycle.

What are the differences between unique_ptr and shared_ptr?

unique_ptr is for exclusive ownership, while shared_ptr allows multiple pointers to share ownership of the same resource.
