Hi,

I have been working on this program for a few days.. and I am so far gone I lost myself in my own program. I usually just start from scratch when I get frustrated but there is too much time invested into my heap to give up so I thought I would come here. My assignment is as follows:

Write a program that converts a number entered in Roman Numerals to decimal. Needs to consist of a class called romanType and an object that does the following:

Store the number as a Roman numeral
Convert and store the number into decimal form
Print the number as a Roman numeral or decimal number as requested by user

The decimal values of the roman numerals are:
M = 1000
D = 500
C = 100
L = 50
X = 10
V = 5
I = 1

After completion, I need to test the program with the following input: MCXIV, CCCLIX, MDCLXVI

Here's what I have so far in the source file:

Code:
//romanType.cpp

#include <iostream>
#include <iomanip>
#include "romanType.h"

using namespace std;

int main()
{
    romanType r;
    
    char romanNum;
    char choice;
    int decimal;
    int total;
    
    cout << setw(60) << "Welcome! Please follow the directions below." << endl;
    cout << endl;
    cout << "Please enter a Roman Numeral: ";
    cin >> romanNum;
    cout << endl;
    
    r.setRoman(romanNum);
    r.convertRoman(total);
         
    cout << "Do you want to see the [R]oman Numeral or the [D]ecimal? ";
    cin >> choice;
    cout << endl;
    
    if(choice == 'R' || choice == 'r')
          r.printRoman(romanNum);
    else if(choice == 'D' || choice == 'd')
          r.printDecimal(total);
    else
          cout << "That was not an invalid choice.." << endl;
    
    cout << endl;
    
    system("pause");
    return 0;   
}//End main


Here's what I have so far in the implementation file:
Code:
//  romanTypeImp.cpp

#include <iostream>
#include "romanType.h"

using namespace std;

romanType::romanType()
{
                                
}//End romanType Constructor

romanType::romanType(char)
{
     char romanNum;              
}//End romanType(string) Constructor

romanType:: ~romanType()
{

}//End ~romanType Destructor

void romanType::setRoman(char)
{
     char romanNum;
}//End getRoman

int romanType::convertRoman(int& total)
{
     int len = strlen(romanNum);
     int count[len];
     
     for(int i = 0; i > len; i++)
     {           
           switch(romanNum[i])
           {
                 case 'M':
                      count[i] = 1000;
                      break;
                 case 'm':
                      count[i] = 1000;
                      break;
                 case 'D':
                      count[i] = 500;
                      break;
                 case 'd':
                      count[i] = 500;
                      break;
                 case 'C':
                      count[i] = 100;
                      break;
                 case 'c':
                      count[i] = 100;
                      break;
                 case 'L':
                      count[i] = 50;
                      break;
                 case 'l':
                      count[i] = 50;
                      break;
                 case 'X':
                      count[i] = 10;
                      break;
                 case 'x':
                      count[i] = 10;
                      break;
                 case 'V':
                      count[i] = 5;
                      break;
                 case 'v':
                      count[i] = 5;
                      break;
                 case 'I':
                      count[i] = 1;
                      break;
                 case 'i':
                      count[i] = 1;
                      break;
           }//End switch     
           total = total + count[i];
     }//End for
  
     total = 0;

     for (int i = 0; i < len-1; i++)
     {
          if(count[i] < count[i+1])
                 total = total - 2 * count[i];
          }//End for          
}//End convertRoman

void romanType::printRoman(char romanNum) const
{
     cout << "Here is your number displayed in Roman Numeral form: " << romanNum << endl;
}//End printRoman

int romanType::printDecimal(int& total)
{
     cout << "Here is your number displayed in Decimal form: " << total << endl;
}//End printDecimal



And here's what I have so far in the header file:

Code:
//romanType.h

using namespace std;

class romanType
{
public:
       void printRoman(char) const;
       int printDecimal(int&);
       void setRoman(char); 
       int convertRoman(int&);
       
       romanType();
       romanType(char);
       ~romanType();
        
private:
       char romanNum[6];
       int decimal;
       int total;
};//End Class romanType

If anyone can offer any guidance, that would be much appreciated! I apologize for my code being a mess.. I got frantic and started throwing things in to see if I could get something to work and now I don't know what to keep, what to lose, and what to change.

Thanks for any help you guys can offer!
