Dynamic_Cast is a type-safe casting operator in C++ that allows you to safely convert pointers or references of base class types to derived class types. It is particularly useful in scenarios involving polymorphism, where you want to ensure that the object being cast is indeed of the derived type. If the cast is not valid, Dynamic_Cast returns a null pointer for pointers or throws a std::bad_cast exception for references. To use Dynamic_Cast, the base class must have at least one virtual function, enabling runtime type identification. This ensures that the cast checks the actual object type at runtime, providing a safeguard against incorrect type conversions.
