Virtual Functions in C++

Important points about Polymorphism and Virtual Function   Polymorphism is the third important feature in C++ after data abstraction and inheritance. Polymorphism means single name and multiple meaning. There are two types of polymorphism like compile time polymorphism and run time polymorphism. We can achieve compile time polymorphism using the function and operator overloading. We can achieve run time polymorphism using the virtual functions. In case of function overloading we can write the multiple function having same name inside a single class. And when we call that function the call is bind with…Read more
