well, as this seems like a blatant request for homework answers, my answer is 'no'. i mean, if you are in such a hurry that you cant even take the time to type complete words or sentences then i think i would waste your time.

if you want your answer now, do a search on this site as im sure it has been answered before. if not here then google might have a page or two about it, give it a search. if you want to learn how to do it, then show some effort. think about how these number systems work, give an attempt, draw it on paper. whatever you do, post back with some attempts.

decimal and hex is the same, just another representation of the same thing

Code:

int i=10;

This is stored as 10 decimal or 0x0A hexadecimal. Have a look at the printf() functions if you want to present the data to a user. If you have to convert user input, have a look at the strtol() / strtoul() functions.
