[snip...] I think perhaps you should have looked at the original :) This whole discussion dervise not from a discussion of production code, but from a contrived problem designed to test an interviewee's understanding of some of the more difficult bits of C++ (legit, because the interviewees had rated themselves (probably incorrectly) as highly skilled C++ programmers). In the event what he is trying to do is to take two different, non- exception safe, classes, derived from the same base, and change one of them into the other using an assignment operator. Not surprisingly, this is difficult, and I suspect not something you would come across very often, and not something I personally would accept in a program design, regardless of the language being used. alan -- http://www.ibgames.net/alan Registered Linux user #6822 http://counter.li.org Winding Down - Weekly Tech Newsletter - subscribe at http://www.ibgames.net/alan/winding/mailing.html
