What are some advanced pointer concepts in C++?

Advanced pointer concepts in C++ include smart pointers, pointer arithmetic, and function pointers. Would you like to explore any specific concept?

Can you explain smart pointers?

Sure! Smart pointers, like std::unique_ptr and std::shared_ptr, manage memory automatically, helping to prevent memory leaks.

What is the difference between unique_ptr and shared_ptr?

std::unique_ptr allows only one owner of the resource, while std::shared_ptr allows multiple owners, using reference counting.

How does pointer arithmetic work?

Pointer arithmetic involves adding or subtracting integers to/from pointers, allowing you to navigate through arrays efficiently.

Can you give an example of using function pointers?

Certainly! Function pointers can be used to store the address of a function and call it dynamically, which is useful for callbacks.
