What is automatic memory management in C++?

What is automatic memory management in C++?

Automatic memory management in C++ refers to the process where the system automatically handles memory allocation and deallocation, reducing the risk of memory leaks.

How does it differ from manual memory management?

In manual memory management, the programmer explicitly allocates and deallocates memory using operators like new and delete. In contrast, automatic memory management often uses smart pointers or garbage collection to manage memory automatically.

Can you give me an example of automatic memory management in C++?

Sure! Using smart pointers like std::unique_ptr or std::shared_ptr allows C++ to automatically manage memory. For instance, when a std::unique_ptr goes out of scope, it automatically deallocates the memory it owns.

Are there any downsides to using automatic memory management?

Yes, while it simplifies memory management, it can introduce overhead and may not be as efficient as manual management in performance-critical applications.
