c++ inheritance
Author
Hi.
I''ve been experimenting some with classes, and I have a small problem I''ve been fighting with for 3 days now. Help is very appreciated. =)
Basically, I have a class:
class a
{
protected:
int iAVar;
};
Then I have another class inheriting it..
class b : a
{
// Stuff, nothing of importance for this problem.
};
And then last, and this is where my problem is(either here or in "a"..
class c : b
{
public:
void DoStuff() { iAVar = 2; }
};
However, this gives me this:
error C2247: ''iAVar'' not accessible because ''b'' uses ''private'' to inherit from ''a''
Anyone got any ideas? And yes, this code is faked, but I could give you the real thing if you want.
Thanks.
Eric
unless you do state it explicitly, its assumed its private.
ex.
class a
{
protected:
int i;
};
class b: public a
{
};
class c : private b
{
void do_it()
{
i = 0;
}
};

class c : public b
{
public:
void DoStuff() { iAVar = 2; }
};
that should work
{
protected:
int iAVar;
};
class b : public a
{
// Stuff, nothing of importance for this problem.
};
class c : public b
{
public:
void DoStuff() { iAVar = 2; }
};
that should work
what about encapsulation?
why do you have a protected member?
best to make it private and manipulate with protected member functions if you only want derived classes to access it.
