Loop in general or "for each" style loop, that's huge difference.
The 2nd one has a lot to do with collections.

Yes, it is not crazy when you're looking at it from the reverse engineering / implementation side
but if you start thinking about it from user's perspective then it is very bad behaviour
because they used "foreach" like loop which is a concept of walking thru every element of collection.
- kweingar 3y agoI still don't see how looping over a collection is different from looping over a sequence of numbers from 1 to n.
- tester756 3y agoDepends what do you actually mean by sequence, but mostly purpose. Normal "for" is like: repeat this code body as long as condition is satisfied Foreach is more like: walk thru this collection Look (c#): foreach (var item in items) ... for (int i=0; i<10; i++) { } In the 2nd version it is possible to jumps ahead, back, do not move, etc. Generally play around "i's" values Meanwhile I haven't seen yet any1 trying to do anything like this in foreach, because it is meant for just walking thru collection
