JavaScript supports HTML DOM; so […]
C++ allows virtual functions to resolve function calls at run-time. This is called late-binding. Like virtual functions, C++ allows virtual destructors to delete the objects properly in an inheritance hierarchy. C++ allows calling virtual functions from class destructors. But what will happen when it calls these virtual functions from class destructors? Let’s take an example, […]

Virtual keyword in C++ is used for polymorphic behavior. C++ allows the creation of virtual functions, virtual destructors, and virtual inheritance. Virtual functions will resolve exact function calls in the inheritance hierarchy, at run-time. This is called late-binding. That means, what function to call will come to know at run-time instead of compile time. // […]
