Question

ok so in the question i am missing "C". just add it in here. I am not sure where i missed it at

Write a program that converts a number entered in Roman numerals to
decimal. Your program should consist of a class, say, romanType. An
object of type romanType should do the following:

a. Store the number as a Roman numeral.

b. Convert and store the number into decimal form.

c. Print the number as a Roman numeral or decimal number as requested
by the user.

The decimal 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.
#include <iostream>
using namespace std;

class romanType{
public:
romanType(char&); // ** make constructor
int convert();
void print();
void get();

private:
int M, D, C, L, X, V, I;
char romanNumeral;
};
romanType::romanType(char &ch){
M = 1000;
D = 500;
C = 100;
L = 50;
X = 10;
V = 5;
I = 1;
cout << ch << endl;
romanNumeral=ch; // ** set up romanNumeral
}
int romanType::convert()
{
if (romanNumeral == 'M')
{
return 1000; // ** return value
}
else if(romanNumeral == 'D')
{
return 500;
}
else if(romanNumeral == 'C')
{
return 100;
}
else if(romanNumeral == 'L')
{
return 50;
}
else if(romanNumeral == 'X')
{
return 10;
}
else if(romanNumeral == 'V')
{
return 5;
}
else if(romanNumeral == 'I')
{
return 1;
}
return 0; // ** error -
}
void romanType::print()
{
cout << romanNumeral << endl;
}
void romanType::get()
{
}
int main(){

char romanNumeral;

cout << "Welcome to the Roman numeral to decimal converter! Please enter a number in Roman numerals to be converted: ";

cin >> romanNumeral;

romanType roman=romanType(romanNumeral); // ** set up value

cout << roman.convert() << endl;;

system("pause");

return 0;

Print The Roman Numeral
r.printRoman();
Print The Decimal Form Of Numeral
r.printDecimal();
}

Program:

===============================================

#include<iostream>
#include<string.h>
using namespace std;
class romanType
{
    private: char rn[100];
    int dn;
    public:romanType()
    {
        int i;
        for(i=0;i<100;i++)
        {
            rn[i]='';
        }
        dn=0;
    }
    public:romanType(char n[])
    {
        strcpy(rn,n);
        dn=0;
    }
    public: void romanToDecimal();
    public: int toDecimal(char);
    public: void printRoman();
    public: void printDecimal();
};
void romanType::romanToDecimal()
{
    int i=0;
    int s=toDecimal(rn[i]);
    while(rn[i])
    {
        if(s>=toDecimal(rn[i]))dn = dn+toDecimal(rn[i]);
        if(s<toDecimal(rn[i]))dn = dn-s+(toDecimal(rn[i])-s);
        s=toDecimal(rn[i]);
        i++;
    }
}
int romanType::toDecimal(char symbol)
{
   if (toupper(symbol) == 'I')
      return 1;
   else if (toupper(symbol) == 'V')
      return 5;
   else if (toupper(symbol) == 'X')
      return 10;
   else if (toupper(symbol) == 'L')
      return 50;
   else if (toupper(symbol) == 'C')
      return 100;
   else if (toupper(symbol) == 'D')
      return 500;
   else if (toupper(symbol) == 'M')
      return 1000;
   return 0;
}
void romanType::printRoman()
{
    cout<<" The roman number is: "<<rn;
}
void romanType::printDecimal()
{
    cout<<" The decimal number is: "<<dn;
}
int main()
{
    char a[100];
    cout<<"Enter the roman number: ";
    cin>>a;
    romanType r1(a);
    r1.romanToDecimal();
    r1.printRoman();
    r1.printDecimal();
}
