Answer:

Yes, the virtual function can be private. Let see an example code,

#include<iostream>
using namespace std;
class Base
{
public:
    void test();
private:
    //private virtual function
    virtual void fun()
    {
        cout << "Base Function"<<endl;
    }
};
class Derived: public Base
{
public:
    void fun()
    {
        cout << "Derived Function"<<endl;
    }
};
void Base::test()
{
    Derived objDerived;
    Base *ptr = &objDerived;
    ptr->fun();
}
int main()
{
    Base Obj;
    
    Obj.test();
    
    return 0;
}

Output: Derived Function
