I told him he needs to use descriptive variables and he told me he likes to be annoying to the TA's (graders). I guess he doesn't realize they give him a grade on that stuff.

It is surprising how many people try to do that. I used to occasionally help mark code at university for extra beer money and if I couldn't understand it reasonably quickly then they got marks deducted. One guy used a single word as a variable but kept varying which chars were upper and lower case. The code worked but one of the criteria was to have readable code so his mark dropped like a stone. Probably should have submitted that one to the obfuscated C contest...
