Explain move semantics in C++ (C++11) in detail. Cover the concept step by step and explain why it is needed, how it works, and where it is used. Then, write a complete class implementation demonstrating move semantics, ensuring that all relevant special member functions are implemented, including: Default constructor Destructor Copy constructor Copy assignment operator Move constructor Move assignment operator Explain the purpose of each function, when it is invoked, and how resource ownership is transferred safely without memory leaks or double deletion.
