Hi all,
In the file simple.h there is a class declaration as follows
class Sink:public BuferedTransformation
{
protcted:
//data and function members in the class BufferedTransformation
//which are public in BufferedTransformation
}
The comment together with the class is --- // make these functions
protected to help prevent unintentional calls to them
I would like to know what exactily is intended. Is it to restrict the use
of the data and function members in the base class.
If it is so then..........
Actually i have a simple cpp file which tries to do the same. But I am able
to access the functions in protected
area from main() using an object of the derived class.
#include<iostream.h>
class Base
{
public:
int get(int a, int b)
{
return(a+b);
}
};
class der:public Base
{
protected: //this is what i am mentioning about . why is it done
so
Base::get;
};
int main()
{
der obj;
cout<<"result is"<<obj.get(12,13)<<endl; //am able to access the
function which is protected in der class
}
So why is it done so? Or is my interpretation wrong?
Thanks and regards
Ramesh V Nair
