Question

Questions are Object Oriented Programming with C++ related

1. Write a syntax to declare a static data member named count of a class named Base.

2. Can polymorphism be used with protected inheritance in C++? why or why not?

3. With a given code, how will you check whether the code applies polymorphism correctly?

Answer 1

Question#1

#include<iostream>

using namespace std;

class base {

static int count;

};

Question#2

Yes we can use polymorphism for the protected variables as we can use them as we have declared that class publically to the other class so in that we can access their variables very easily

Question#3

The main symbol of checking that the class applies the polymorphism concept or not is that you can check it through by seeing if in the class inheritance is done and the declaration of virtual and pure virtual function is been used so through it we can detect that the polymorphism is been used in the code.
