Really?  I personally find having all variables grouped together
much easier to understand.  Stumbling across declarations in the
middle of the code in a for-loop, for example, takes me by surprise.

I also greatly dislike initializing variables in their declarations.

Maybe I'm just old fashioned since I have been writing C-code for
more than 30 years.
