I meant this:
let me explain it like this.
I have *virtual int speed()* in class A.(in file A.h)
I inherited class in class B(in file B.h) as class B:public A
class B have a private member m_speed.
Now I have to return m_speed from speed() from class B as I would
instantiate an object of class B to use it.
So if write my prgram like this:
class B:public A
{
private:
int m_speed();
}
int B::speed()
{
return m_speed;
}
would it work ?
