hi there.! can someone help me to construct the code of this problem..
Write a program that accepts a number as a Roman numeral and outputs the
equivalent Arabic (ordinary) numeral. Assume that the Roman numeral is 50 or
smaller (Roman numeral L or smaller)
heLp....
What have you coded so far?
Mainframe assembler programmer by trade. C coder when I can.
For every I, V, X, L you find in the string, add 1, 5, 10, 50 to a sum respectively.
Maybe it's easier to go right-to-left... that way if you encounter a unit that's less than the one you just processed, SUBTRACT it instead of ADD.
This process does not ensure the legality of the Roman numeral but it will work for any legitimate ones. I understand that one cannot do VL for example for 45 but I guess you are not asked to validate input.
