I'm having trouble getting this program to work for roman numeral conversion. I hope it says that i have one error, which is C2110: cannot add two pointers. here's what i have so far... ANY help would be great, thanks a bunch! :)

```
#include <iostream>
using namespace std;
int main()
{
//Type in an integer between 1 and 4000
int numToConvert;
cout << "Enter an integer between 1 and 4000";
cin >> numToConvert;
int th,h,t,o;
char thousands[] = {"", "M", "MM", "MMM", "MMMM"};
char hundreds[] = {"", "C", "CC", "CCC", "CD", "D", "DC", "DCC", "DCCC", "CM"};
char tens[] = {"", "X", "XX", "XXX", "XL", "L", "LX", "LXX", "LXXX", "XC"};
char ones[] = {"", "I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX"};
if (numToConvert<=4000){
int romanNumber;
th = numToConvert / 1000;
numToConvert = numToConvert % 1000;
h = numToConvert % 100;
t = numToConvert / 10;
o = numToConvert % 10;
romanNumber = romanNumber + thousands[th] + hundreds[h] + tens[t] + ones[o];
cout << "The roman number for this integer is " << romanNumber;
}
else
{
cout << "Invalid number, please enter a new number between 1 and 4000";
return 0;
}
}
```
