private inheritance

[Tony Johansson]

Hello!

Private inheritance is sometimes called implementation inheritance.
If you use this private inheritance how is with the usage of overriding
then.
Is overriding used less often when having private inheritance then when you
have public inheritance.

I just want to have you opinion about this matter.

You could say that private inheritance almost always
involves overriding private base class' methods, b/c
that's one of the two scenarios where you can't use
composition instead (the other one being access to
protected members).

As to the comparison with the amount of overriding going
on in public inheritance: I have no clue. Take a large
real-world project and measure, I guess.
