why are we only using I in loops?

its a real question why only I ? I used f it was so cool.
Use other letters for your loops. I’m onto something guys, it’s the next big thing.

P.S: I’m going to take a break from coding in C since its pretty anoying and im not really doing anything while working maybe this challenge is really too hard for me.
I’m maybe going to start another project then see.
