What are advanced pointers in C++?

Advanced pointers in C++ include concepts like smart pointers, function pointers, and pointers to pointers. They enhance memory management and flexibility.

Can you explain smart pointers?

Smart pointers are objects that manage the lifetime of dynamically allocated memory. They automatically deallocate memory when it's no longer needed, preventing memory leaks.

What are the different types of smart pointers?

The main types of smart pointers in C++ are std::unique_ptr, std::shared_ptr, and std::weak_ptr. Each serves different purposes in memory management.

How do I use a function pointer?

To use a function pointer, you declare a pointer with the function's signature, assign it to a function, and then call the function through the pointer.

Can you give an example of a pointer to a pointer?

Sure! A pointer to a pointer is declared as int** ptr. It can be used to manage multi-dimensional arrays or to modify the address of a pointer.
