why it can be assign "0", but can't compare with "0"?
The iterator type in 'map' is implementation-defined. What
it means to initialise it with (int)0 is implementation-defined.
Why operator != (int)0 doesn't work is (you guessed it!)
implementation-defined. You need to either look at the code
in the debugger to see what's going on or ask in the newsgroup
dedicated to your implementation (microsoft.public.vc.* family
of newsgroups come to mind).
