Finding new iterator name makes my life a bit miserable. How do you find name to your iterator ?

Answer 1

I want write meaningful iterator’ name

Then the name you use should reflect the meaning of what the iterator is used for.

For example if you are looping over products inside a loop of categories inside a loop of catgegory-groups, you might use names like producti, categoryi, groupi, perhaps together with number-of-item names likes productn/categoryn/groupn and/or array names like products/categories/groups.

I’d only use i for the simplest short non-nested loops that one can understand with a quick glance. Personally I wouldn’t even use j; when loops are nested that usually calls for more self-explanatory variable names.
