If access modifier of base class member function is protected OR public, you can do call member function of base class from derived class. Call to the base class non-virtual and virtual member function from derived member function can be made. Please refer the program.

#include
using namespace std;

class Parent
{
  protected:
    virtual void fun(int i)
    {
      cout<<"Parent::fun functionality write here"<

Output:

$ g++ base_function_call_from_derived.cpp
$ ./a.out 
Child::fun partial functionality write here
Parent::fun functionality write here
Parent::fun3 functionality write here
Child::fun1 partial functionality write here
Parent::fun1 functionality write here
