Description

Using Protected Members to let base classes provide derived classes with access to some of their private member data or functions.

Demo Code

#include <cstdlib> 
#include <iostream> 

using namespace std; 

class base // w w  w  . ja va2 s  .  co  m
{ 
protected : 
    int anInt; 
}; 

class derived : public base 
{ 
public : 
    void AFunction(int theInt); 
}; 

inline void derived ::AFunction(int theInt) 
{ 
    anInt = theInt; 

    cout << anInt << endl; 
} 

int main(int argc, char *argv []) 
{ 
    derived temp; 

    temp.AFunction(5); 

  
    return 0;
