multiple iheritance

> if not removed totally .........but why?

We need to take a small example with some classes.

A
/ \
/ \
B C
\ /
\ /
D

Let's consider this simple example where B and C inherit from A and D inherits from B&c (typical combination of C++'s hierarchical and multiple inheritance). For this discussion let's not consider the hierarchical inheritance. Consider the multiple inheritanace, if the child class D has to get a handle of grandparent, A, then, it can achieve it through two ways viz.,

one of its parent B and through
another parent C

Now, D has a duplicate reference to access its grandparent A, just in order to avoid this chaos.....

Hope you got it
