Mastering std::move and std::forward: A Deep Dive into C++ Value Categories

This article explains the concepts of lvalues and rvalues in C++, how std::move converts a named object into an rvalue to enable move semantics, and how std::forward preserves the original value category for perfect forwarding in template functions, illustrated with clear examples and code snippets.
