There’s nothing special about a generic for loop (at least in C-like languages). There’s no reason you couldn’t do something like for (i = 0; true; i++) to make it infinite. Some languages even support an infinite list generator syntax like for i in [0..] (e.g. it lazily generates 0, then 1, then 2, etc. on each iteration) so you can use a for-each style loop to iterate infinitely.
Now, whether or not you should do such things is another question entirely. I won’t pretend there aren’t any instances where it’s useful, but most of the time you’re better off with a different structure.

Try not to excessively repost, as a rule of thumb, wait at least 2 months to do it if you have to.
I disagree. It’s a while loop, because a for-loop is finite, so you can’t count to infinity with it.

there is no reason for a (non-foreach) for loop to be any more or less finite than a while loop.
is just syntactic sugar for
in most or all languages with c-like syntax.
for (i=0; true; i++)I wanna see how you get a while loop to actually go to infinity. I’ll wait…
on second thought, no I won’t.
