Virtual Function | Abstract Class in C++ | Program

Virtual Function | Abstract Class in C++ | Program *Abstract Class in C++:* An abstract class is a class that cannot be instantiated on its own. It contains at least one pure virtual function, denoted by "= 0", making it mandatory for derived classes to implement these functions. Abstract classes serve as base classes providing a blueprint for derived classes. *Virtual Function in C++:* Virtual functions enable polymorphism in C++. They are declared in a base class and can be overridden by derived classes to provide their own implementation. Using the `virtual` keyword allows dynamic binding, meaning the appropriate function gets called based on the object type during runtime. Combining these concepts, you use an abstract class to define a base structure with pure virtual functions, and virtual functions enable derived classes to implement their own versions, allowing polymorphic behavior.
