Yes, this is homework. 
I have the basic idea. I know that basically I need to introduce a for loop and set if's saying if the value is above 9 then it's a, b, c, and so forth. But what I need is to get the for loop to grab the integer and its index number to calculate and go back and forth and then print out the hex. by the way its an 8 bit binary number and has to come out in two digit hex form.

thanks a lot!!
