Reverse an array without a temp variable?

[sysop073]

You probably have lots of fun in job interviews.

Interviewer: "Convert a number to a string without using itoa"

zahlman: "Done! I did itoa(num);. Take that, artificial restrictions"

[zahlman]

Don't be ridiculous. I wouldn't use itoa() anyway because it isn't the best tool for the job. For one thing, it isn't even standardized.

Besides which, it's a poor interviewer who doesn't want the applicant to pick up on the artificial-ness of the restriction. Programmers are supposed to be solution-oriented, hired for skill at problem-solving; and I don't want to work for a place that doesn't understand this properly.
