Actually only a recent change in C. Its always been true of C++.
But in C up until recently(*) you couldn't define a loop
variable in the loop it had to be outside:

int x;
for (x=0;....)

(*)I'm not sure whether the C++ style loop definition was 
introduced in the original ANSI standard or the later 
revision (none of my books malke it clear), but I think it was 
the revision.

But C++ always had loop variables as part of block scope.

Sory for any confusion,
