![]() In that case, it generates an error message “Source type is not polymorphic”. Suppose If we do not use the virtual function, then what is the result? In figure 1 Casting from Derived class 2 pointer/reference to the “Base class” pointer/reference showing Upcasting (Derived class 2 -> Base Class).Īs we mention above for dynamic casting there must be one Virtual function. Upcasting: Casting a derived class pointer (or reference) to a base class pointer (or reference) is known as upcasting.In figure 1 casting from the Base class pointer/reference to the “derived class 1” pointer/reference showing downcasting (Base ->Derived class). Downcasting: Casting a base class pointer (or reference) to a derived class pointer (or reference) is known as downcasting.A dynamic_cast works only polymorphic base class because it uses this information to decide safe downcasting. To work on dynamic_cast there must be one virtual function in the base class. In C++, dynamic casting is mainly used for safe downcasting at run time.

The film stars Michael Oliver, John Ritter, Jack Warden, Amy Yasbeck, and Ivyann Schwan. Unlike the previous film, this film is rated PG-13. It does things like implicit conversions between types (such as int to float, or pointer to void*), and it can also call explicit conversion functions (or implicit ones).ĭynamic Cast: A cast is an operator that converts data from one type to another type. Problem Child 2 is the 1991 comedy film sequel to Problem Child. This makes him the only person to appear in all movies and the cartoon, besides Jack Warden who appeared in all movies, but not the.
