Answer
std::move performs a cast that produces an xvalue expression; it does not move data by itself. • The resulting expression can select a move constructor or move assignment operator. • If no suitable move operation exists, copying may still occur. • Do not use an object’s previous value after moving unless its documented state permits it.
💡 C++ Example
std::string source = "hello";
std::string destination = std::move(source);
