Thread: Accessing members of parent class

If I have two different classes that are both derived from the same parent class, is it possible for one class to access the parent members of the other class? Example:

Code:

#include <iostream>
using namespace std;

class Parent
{
    protected:
        int value;
};



class Child_A : public Parent
{
    public:
        void Foobar(Parent &other) { cout << other.value << endl; }
};



class Child_B : public Parent
{
    
};



int main()
{
    Child_A a;
    Child_B b;

    a.Foobar(b);
    return 0;
}

This gives me "int Parent::value is protected". Is it possible in another way?
