What are some advanced memory management techniques in C++?

In C++, advanced memory management techniques include smart pointers, custom allocators, and memory pools. Would you like to know more about any specific technique?

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, helping to prevent memory leaks. The most common types are std::unique_ptr, std::shared_ptr, and std::weak_ptr.

How do I use std::shared_ptr?

To use std::shared_ptr, include the header <memory>, then create it using std::make_shared<T>(). It allows multiple pointers to share ownership of an object, and the object is deleted when the last shared_ptr pointing to it is destroyed.

What are the advantages of using smart pointers over raw pointers?

Smart pointers provide automatic memory management, reducing the risk of memory leaks and dangling pointers. They also offer better exception safety and can simplify ownership semantics.
