#include <iostream>
    using namespace std;
    class ClassA
    {
        public:
        virtual void example() = 0; 
    };
    class ClassB:public ClassA
    {
        public:
        void example()
        {

            cout << " is awesome.";
        }
    };
    int main()
    {
        ClassA* array[2];
        ClassB B;
        ClassC C;
        array[0]=&B;
        array[1]=&C;
        array[0]->example();
        array[1]->example();
