Roman Numerals

[Adrian]

Here is my problem:

Input: Roman Numerals (M=1000, D=500, C=100, L=50, X=10, V=5, I=1)
Ouput: Roman Numerals converted.
The program asks the user to enter two roman numbers to be added.
How do I convert these numerals into reg. numbers?
How do I convert a reg. number into a roman numeral?

Thank for the HELP.

The easiest way is to to read the numbers as a char and compare it to values
with switch() case. But the numbers can't added simply by checking its values
because I and X is as reg. number 9. So you have the compare both numbers
and if the first one is lower than the second subtract the first from the
second. The comparison could be made in a function you call when you need
it.

Hope this helps
