how do you write a program that converts a number entered in Roman numerals to decimal?
The dicimal values of the roman numerals are
M 1000
D 500
C 100
L 50
X 10
V 5
I 1

First, We don't code for you... we can only help provided you give your code that you need help with
Second, if just your just asking for suggestions then you can use arrays and an if statement to compare the letters to their corresponding number..then do the operations required to match the whole roman numeral counterpart...but that's where it gets complicated

A string for your input.
A string to hold the letters "MDCLXVI".
An array to hold your amounts to correspond to the letters.
Loop through your input string to process the letters one character at a time.
Find the postition of the character in your letters.
Use that as your index of your array.
Total everything up.
Carefull!!! Watch for your 4s (IV), 9s (IX), 40s (XL), 90x (XC), etc.
