Answer:

If a function is defined in a base class and it is not private then it is available in the derived class. You can call it in the derived class using the resolution operator (::). Let see a code where I am accessing the parent class function in the derived class as well as from the derived class object.

#include<iostream>
using namespace std;
class Base
{
public:
    virtual void print()
    {
        cout << "I am from base class" << endl;
    }
};
class Derived :public Base
{
    void display()
    {
        //calling base class function
        Base::print();
    }
};
int main()
{
    //derive class object
    Derived d;
    
    //calling print function
    d.print();
    
    //Calling print function of parent class
    // using derived class object
    d.Base::print();
    
    return 0;
}

Output:

I am from base class

I am from base class
