A useful tip I picked up was to use
iiinstead ofjfor an inner loop. It's far more distinct thanj.If for some terrible reason you have even more inner loops you can easily continue the trend
i,ii,iii,iiii,iiiii- oriv,vif you're feeling romanIf you have the need to nest 5 levels of for-loops, I suggest taking a step back and rethinking your approach, my friend.
Even if that other approach is just refactoring it into separate methods.
I just do i2, i3, etc
Two or three "i"s is readable, but any more and you're counting.
I'Ve started using i, k, m, n that's usually enough.
When you have multiple indices you're also bound to have multiple cardinals those indices count up to, say
foo.lengthandbar.length, sofoo_iandbar_iare perfectly legible and self-documenting. A bit Hungarian but Hungarian is good in small amounts. Unless you're dealing withwidthandheightin which case it'sxandybut it's not thatwidth_iwould be incomprehensible.At this point we might as well go full Roman as you suggested. MXMCIIV to MXMCCVII as indices.
