But I don't like this idiom for several reasons. Sure, it can be
convenient to write:

without having to make an annoying detour to the top of the function to
write that declaration for i. But then you need a second loop, and a
third, and how you have to repeat a declaration each time:

Better to do it once and forget about it.

Then, it allows nested loops like this:

      for (int i = 0; i<B; ++i)

All those i's are different! Only the last is accessible in the inner loop.

i never used nor even seen this with 3 i..for me as i said "loop" iteslf not neccessary belongs to inside of the loop more like the outside..
here liek this this is misleading that the i is one thing - until someone knows its just internat thing (but i as i said disagree it should be intennal)
