Decimal to Roman Numerals

[ARMAS]

Make a program that allows the user to input a number and aoutput it's
roman numeral equivalent..... plzzzzzz help....
Ex: 109 output:CIX

OK, show us what you've got so far, and we'll make suggestions

I have no idea .... i'm just a feshmen.... maybe i could try but it
wil take me a long time... and i need a quick answer... plzzzz

Quck answer:
DYOH!

I'm asking for help, not a bullshit answer

That is where you are wrong (in both regards).
You are not asking for help. You are asking for someone to do your
homework for you. That is decidedly not helpful for your future but
harmful.
Because of your attitude, I am sure that any code answer you receive
will be rather humorous.

No, you're asking us to do your homework for you.

If you're unable to do it yourself, we'd prefer that you fail the
class.

If you want *help*, we might be able to provide some, but we're not
going to do it all for you.

There are these things called "books". You probably have not heard of them.
They are in:

a)Libraries.

b)Bookstores.

c)Other places.

You may want to explore "books"; specifically a book about the 'C'
programming language.

When you have something resembling a program that you can't get to work,
feel free to post back to this newsgroup.

Also, if you want to hire me to do your program, I will do a "Roman Numeral"
program for USD $1,500. That is probably about $25/line.

There may be others in this newsgroup who will do it for less. I won't be
hurt if you contract with one of them.

 

[Kenneth Brody]

It ain't a homework....

Then what is it? All available evidence says otherwise.

Quoting your previous post:

i'm just a feshmen....

Translation: I'm in school.

maybe i could try but it wil take me a long time...

Translation: I'm lazy.

and i need a quick answer...

Translation: The assignment is due tomorrow.

You've also said you have "no idea" on how to do this. If that's
the case, why are you doing this?

Conclusion: It's homework.

No, no, you don't understand the way we do things here.

Offers of contracts to do homework problems are traditionally done on a
"highest bid" basis; the offer includes a clause that it is invalidated
by anybody posting a higher offer to the thread in which it is made.

I am willing to write a roman numeral converter for the OP for US$2000,
payment in advance by certified check or money order. This offer is
valid until midnight (UTC) this Friday, 2007-01-26, or until a higher
offer is made, whichever comes sooner.

Isn't it also traditional to offer a discount if the solution can be
submitted directly to the instructor?

Either try it yourself or accept that maybe you should have started
this little project a little bit earlier. Plenty of freshmen before
you have figured at least that much out, or possibly gone on to flip
burgers. You still have a choice; I suggest you choose wisely.

 

[user923005]

submitted directly to the instructor?

I already posted a working solution (under conditional compilation it
also uses the bar notation for huge roman numeral values) and thereby
claim all prizes.
I also get the grade, if it is above a C.
However, getting tossed out on your ear for plagiarism I leave to the
O.P. untouched and pristine.

I bid my college tuition for next year - see
http://www.virginia.edu/Facts/Glance_Tuition.htm - plus expenses (I
figure your pry going to want it to run on Alpha systems, so I going to
want one of those to develop on - see
http://h18002.www1.hp.com/alphaserver - hurry, sale ends soon. A SPARC
system might also be nice.) I'll assign the copyrights of the code to
you, but I keep the hardware.

Make a program that allows the user to input a number and aoutput it's
roman numeral equivalent..... plzzzzzz help....
Ex: 109 output:CIX

I wrote a program to do this. I won't give you all of it but I will give
you a framework where you can fill in the algorithm.

#include <stdio.h>
#include <string.h>

/*
Known Roman numerals are:
I=1, V=5, X=10, L=50, C=100, D=500, M=1000
Anything greater is represented by appending '~'s.
Each '~' represents multiplication by 1000.

The length of the input is unlimited.
*/

static const char *rom[] = {
"", "I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX",
"", "X", "XX", "XXX", "XL", "L", "LX", "LXX", "LXXX", "XC",
"", "C", "CC", "CCC", "CD", "D", "DC", "DCC", "DCCC", "CM"
};

int main(int argc, char **argv)
{
size_t i, j, k, len, m, numdig;
const char *p;

if(argc != 2)
{
fprintf(stderr, "Usage requires one argument: "
"a decimal number to convert.\n");
return 0;
}
numdig = strlen(argv[1]);
for(i = 0; i < numdig; i++)
{
j = numdig - i - 1; /* reverse index */

if(argv[1] < '0' || argv[1] > '9')
{
putchar('\n');
fprintf(stderr, "Invalid digit: %c\n", argv[1]);
return 0;
}

/* Add your algorithm here. How to determine
which element of the 'rom' array to
output?

It's all about mathematics. Think about the
values of:

argv[1] - '0'

j % 3

j % 3 * 10

j / 3
*/

}
putchar('\n');
return 0;
}

If this isn't homework, I would love to know how you ended up with such
a project.

 

[Rethish]

Hi;

I would like to learn how the below mentioned program works.

how does ??< evaluate to a '(' and how ??( to '['

could u ppl give a short explanation and if possible point me to some
info I can read to get more info on this.

Thanks & regards
Rethish

 

[Chris Dollin]

I would like to learn how the below mentioned program works.

how does ??< evaluate to a '(' and how ??( to '['

It's (an obscure) part of the definition of C; they're called
"trigraphs". They don't 'evaluate', they represent.

could u ppl give a short explanation and if possible point me to some
info I can read to get more info on this.

Please don't abbreviate "you" and "people" like that. It makes
your text harder to read for old-timers like what I am. There'
no hortage of vowel on Uenet.
