Is a variable named i unacceptable? [closed]

Answer 1

i is definitely acceptable. Not sure what kind of justification I need to make -- but I do use it all of the time, and other very respected programmers do as well.

Social validation, I guess :)

Answer 2

Yes, in fact it's preferred since any programmer reading your code will understand that it's simply an iterator.

Answer 3

I should point out that i and j are also mathematical notation for matrix indices. And usually, you're looping over an array. So it makes sense.
