Question

write a c++ program to demonstrate hierachical inheritance to get square and cube of a number. Base class must calculate square of a number whilst Base class2 caculates cube of a numberr

Answer 1

#include <iostream>
using namespace std;

class Base {
public:
    Base(int n) : number(n) {}
    virtual int Calculate() { return number*number; }

protected:
    int number;
};


class Base2 : public Base {
public:
    Base2(int n) : Base(n) {}
    int Calculate() { return Base::Calculate() * number; }
};


int main() {
    Base *b = new Base(3);
    cout << "Base: " << b->Calculate() << endl;
    delete b;

    b = new Base2(3);
    cout << "Base2: " << b->Calculate() << endl;
    delete b;

    return 0;
}
