No it doesn't.

No, the variable is in scope after its identifier, so it can be used in the
initializer expression, e.g.
int i = sizeof(i); // ok
int i = i+1; // not ok
> The BIG mistake is declaration of VARIABLE from wrong position.
No, C++ does not work the way you think it does.
It's not a bug. It would be nice to get a warning, but it's not easy to do
that.
