C++ :: Roman Numeral Project Using Classes

Here is the problem:"Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following:

a. Store the number as a positive integer.
b. Convert and store the number as a positive integer.
c. Print the number as a Roman numeral or positive integer as requested by the user.

The integer values of the Roman numerals are:

M 1000
D 500
C 100
L 50
X 10
V 5
I 1

d. Test your program using the following Roman numerals: MCXIV, CCCLIX, MDCLXVI."I'm doing the best I can to understand the concept of the class. Here is what I have (which is not much thus far, and nowhere near correct I'm sure).

#include<iostream>
#include<iomanip>
using namespace std;
class romanType {
public:
void getRoman();
