Hi,

 Can someone help me with the following code? I don't understand why
the & (reference...is it called specifier?) is needed with the
pointer.

function header:

void insertAfter(List Cell*& p, int k, int x);

I thought that with the pointer, it is already getting passed by
reference, so why the needed & operator. Isn't this like sending the
address twice?

What am I missing?
Vicki
