Well if you have to write the function that converts numbers into hexadecimal by yourself, try to understand the reuse the function posted by zyrus. Mine use standard library and do not fit for a school project.

There might be something quite close in the Code Snippets.
"One of the methods used by statists to destroy capitalism consists in establishing controls that tie a given industry hand and foot, making it unable to solve its problems, then declaring that freedom has failed and stronger controls are necessary." --Ayn Rand
Use modulus (this operator gets the remainder of a / b) 16 repeatedly to get your digits. Use a while loop while dividing the given number by 16 after modulus (use ints, you want truncation) until the given number becomes less than 16.
ie. You have a number, say 254.
254 % 16 = 14. This is your one's digit.
254 / 16 = 15.875 -> 15 after truncation.
15 % 15 = 15. This is your ten's digit.
As for digits, simply use an array of characters for simplicity. Add the characters to the front rather than the end, of course.
Edit: Whoops, not used to the reply tree here. My bad.
