I am having a promblem with a case statement. I am trying to pass an array of letters to this switch statement so that I can assign calues to it. Whenever I try to call the function that has the switch statement
it does nothing and theprogram ends. I would apperciate any advice that can be offered, Below is my code.
#include<iostream>
#include<iomanip>
#include<string>
using namespace std;


void returnRoman(char roman[]);      
void returnArabic(char roman[], int arabicNum);
void checkInput(char roman[]);

class romanType
{
      // 0 < num < 3999
public:
      void returnRoman(char roman[16]);                              //Returns a roman numeral
      void returnArabic(char roman[16], int arabicNum);      //Returns a arabic number
      void checkInput(char roman[16]);                              //Checks to see if the roman numeral is in the proper
                                                                                    //form

private:
      int arabicNum; //The variable that stores the arabic number


}; //class romanType

void main()
{
      int index      = 0;
      int arabicNum = 0;
      char roman[16];
      romanType romanNumeral;

      for(index = 0; index<16; index++)
            {
                  roman[index] = 0;
            }
      
      
      cout << "Please enter a roman numeral that you would like to convert." << endl;
      cout << "Make sure that the numerals are in uper-case only." << endl;
      cout << "Enter in the upper-case 'Q' when finished entering numerals." << endl;
      
index = -1;      

      while(roman[index] != 'Q')
            {
                  index++;
                  cin.get(roman[index]);
                  
            }      
      
      
      //romanNumeral.returnArabic(roman, arabicNum);
            romanNumeral.returnRoman(roman);
      
      

      return;
}//function main

void romanType::checkInput(char roman[])
{
      


      return;
}//function checkInput

void romanType::returnRoman(char roman[])
{
      int index = 0;
      
            for(index = 0; index<16; index++)
      {
            cout << roman[index];
      }

      return;
}//function returnRoman

void romanType::returnArabic(char roman[], int arabicNum)
{
      int index = 0;
      int value = 0;
      
      
while(roman[index] != 'Q')
{
      switch (roman[index])
      {
                          case 'M': case 'm':
                              value = 1000;
                                          break;
                  case 'D': case 'd':
                              value = 500;
                                          break;
                  case 'C': case 'c':
                              value = 100;
                                          break;
                  case 'L': case 'l':
                              value = 50;
                            break;
                  case 'X': case 'x':
                              value = 10;
                                          break;
                  case 'V': case 'v':
                              value = 5;
                                          break;
                  case 'I': case 'i':
                              value = 1;
                                          break;
                         
                        arabicNum = value + arabicNum;
                        index++;
      
      }//end of switch structure
}//end of while loop
      

cout << arabicNum << endl;
      return;
}//function returnArabic
