Copy-and-swap is an elegant technique for implementing assignment operators that provides strong exception safety and eliminates code duplication by leveraging the copy constructor and a non-throwing swap function.

The non-copyable idiom prevents objects from being copied, ensuring unique ownership of resources. Essential for RAII types managing exclusive resources like file handles, mutexes, or database connections.

Pimpl (Pointer to Implementation) separates a class's interface from its implementation by moving private members into a separate implementation class. This reduces compilation dependencies and provides better encapsulation.

RAII is a fundamental C++ idiom where resource lifetime is tied to object lifetime. Resources are acquired in constructors and released in destructors, ensuring automatic cleanup and exception safety.
