Granting Access In C++

When a base class is inherited as private, all public and protected members of that class become private members of the derived class. However, in certain circumstances, you may want to restore one or more inherited members to their original access specification.

Syntax:

class base class

{

private:

----------

public:

---------

};

class derived: public base class

{

baseclass::member1;

baseclass::member2;

baseclass::function name;

};

Program:

#include<iostream.h>

#include<conio.h>

class base

{

private:

int i;

public:

int j,k;

void set(int x)

{

i=x;

}

int get()

{

return(i);

}

};

class derived: public base

{

public:

base::j;

base::set;

base::get;

int a;

};

void main()

{

derived db;

db.j=20;

db.a=40;

db.set=(10);

cout<<db.get()<<” “<<db.j<<” “<<db.a;

getch();

}

Output:

10   20    40
