- C++ ownership model involves creating, destroying objects, and transferring ownership.
- RAII (Resource Acquisition Is Initialization) automates resource management by tying resource lifecycle to object lifetime.
- Destructors in C++ clean up resources when an object's lifetime ends, crucial for preventing memory leaks.
- Lifetime of objects and references must be managed to avoid dangling references and undefined behavior.
- Move semantics in C++ allow efficient transfer of resources from temporary objects, reducing unnecessary copies.
- std::move casts an object to an rvalue reference, enabling move semantics but doesn't move resources itself.
- Understanding ownership is essential for writing efficient and bug-free C++ programs.
