1. What is move semantics?

  • Move operation
  • Resource transfer
  • Transfers resources instead of copying
  • Ownership transfer
Show answer

Answer: Transfers resources instead of copying. Move semantics transfers resources instead of copying. Uses rvalue references (&&). Move constructor and move assignment operator. Improves performance for temporary objects.

2. What is an rvalue reference?

  • Move reference
  • Temporary reference
  • Right reference
  • Reference to temporary object (&&)
Show answer

Answer: Reference to temporary object (&&). Rvalue reference (&&) binds to temporary objects (rvalues). Enables move semantics and perfect forwarding. Distinguishes from lvalue references (&). C++11 feature.

3. What is std::move?

  • Move operation
  • Casts lvalue to rvalue reference
  • Transfer function
  • Moves object
Show answer

Answer: Casts lvalue to rvalue reference. std::move casts lvalue to rvalue reference, enabling move semantics. Doesn't actually move anything. Indicates object can be moved from. Use with caution.
