Abstract classes cannot be used to instantiate objects and serves only as an interface. Attempting to instantiate an object of an abstract class causes a compilation error. Thus, if a subclass of an ABC needs to be instantiated, it has to implement each of the virtual functions, which means ...

Virtual functions are an integral part of polymorphism in C++. To learn more, check our tutorial onC++ Polymorphism. Example 1: C++ virtual Function #include<iostream>usingnamespacestd;classBase{public:virtualvoidprint(){cout<<"Base Function"<<endl; } };classDerived:publicBase {public:voidprint...
