    I normally throw spaghetti up against the wall. Then, when I see an interesting pattern, I write it down. And that's how I discover new letters. Coming up with the pronunciation for those letters is a little difficult though. :rolleyes:

      Give the spaghetti to someone who eats with their mouth open and listen to the interesting sounds that emerge :)

        Much like hungarian notation, which I happen to like (I'm not hungarian), but am slowly being converted to camelCase (I'm not a camel either).

                    The possibilities are transcendental when you get David and Ryan going on Mathematics. Add in Chris and well... somehow it all equals "i" in the end...:laugh:

I said (I believe I read it in an C K&R book) that it's because it's simply an alias for Index which is what "i" is usually doing in a for loop...?? Someone else says it has to do with: They are from general Summation Notation that, like many other mathmatical notations, worked its way into early languages -- specifically Fortran (remember its FORMula TRANSlation) I never would have guessed :P Cheers :) It's frustrating being a genius and living the life of a moron!!! -- modified at 21:18 Wednesday 4th October, 2006

                            It started here:   n  Σ  i=0 the mathematical equivalent to:

                            for (i = 0; i <= n; i++) {
                            }

                            Note the terminating condition, as the mathematical expression Σ includes the terminating value.

                                "i" because it's automatically treated as an integer in Fortran--the first of several automatic integer variables, followed by "j", "k", "l", etc. I can't remember how many letters are allocated to be integers.
