How can i make a program that converts Arabic Numbers to Roman Numbers

How can i make a program that converts Arabic Numbers to Roman Numbers. From 1-3999. Please help me.

You could try searching the board.

You'll need to know how "%" works. For example, this would work on 1-5:

Code:

---

switch(n % 5)
{
  case 0:
      printf("V");
      break;
  case 1:
      printf("I");
      break;
  case 2:
      printf("II");
      break;
  case 3:
      printf("III");
      break;
  case 4:
      printf("IV");
      break;
}

---

n % 5 returns the remainder of n / 5.

Google algorithms for this, because I had to do this in Lisp or Haskell or Prolog (one of those useless languages) for my Programming Language Concepts course (I believe it was Lisp, but it was a year ago). So there's definitely algorithms out on the web, I found some just by googling it.

Just google something along the lines of:
program latin number roman

Switch statements are the best, here. Your best bet is to dissect the number and go through it piece by piece.

EDIT:
PS: Make sure you have a thorough understanding of the Roman Numeral System before hitting this up, sure, 1-20 is easy, but make sure you understand the rest pretty thoroughly, take a trip over to the roman numeral wikipedia. I knew I got tripped up by some of the higher numbers and it cost me a decent bit of time until I figured out some issues while working against the higher values.
