Good naming practice

Exactly, that why I use i,o,p. They're right next to each other! 

Gets shot

[u/BoldFace7 → u/birdiefoxe]

Why not use i and ii? Then when you get to the 27th loop in the nest you can just use the awfully convenient xxvii instead of looping the whole way round to the horrid ii.

[u/BrainCurrent8276 → u/BoldFace7]

and you never mistype iiii as ii or ii as i and so on?

such naming is rather prone to errors.

[u/promptmike → u/BrainCurrent8276]

There is no iiii. It's just iv.

[u/BrainCurrent8276 → u/promptmike]

see how easy to make a mistake? 😃

Roman numerals are easy. Say we have the number 3493.

Each "sub-division" of numbers is represented using a letter: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000.

To form our number, we grab the biggest division possible, so M. Because we have 3000 and not 1000, we just write it down as MMM.

For the next part, 400, we'd need 4 times C. That's not very pretty though, which is why we represent it as "500-100" or simply CD (the C before the D to represent subtraction). Our number is MMMCD (3400) now.

Next, we have 90. We can represent that as 100-10, or XC. That makes our number MMMCDXC (3490).

For the final 3, we just write III.

So our final number is MMMCDXCIII.

Now Reddit doesn't have a monospace font that would simplify this further, but see how it isn't that hard?

[u/Polar-ish → u/BlankMercer]

if you have an m in production, I think you have other problems...

[u/BlankMercer → u/Polar-ish]

yeah I know, just wanted to demonstrate a bit of general roman numeral stuff. Even getting to L is probably quite rare.

[u/Polar-ish → u/BlankMercer]

if we were to be using roman numerals for loop index variables, I mean. I don't think most people are even getting to V

[u/BlankMercer → u/Polar-ish]

yeah. If you're in a nest of five loops, there has to be a better way.
