Copy Semantics of std::vector::push_back and Alternative Approaches
This paper examines the object copying behavior of std::vector::push_back in the C++ Standard Library. By analyzing the underlying implementation, it confirms that push_back creates a copy of the argument for storage in the vector. The discussion extends to avoiding unnecessary copies through pointer containers, move semantics (C++11 and later), and the emplace_back method, while covering the use of smart pointers (e.g., std::unique_ptr and std::shared_ptr) for managing dynamic object lifetimes. These techniques help optimize performance and ensure resource safety, particularly with large or non-copyable objects.
