Question

**c++***

Write a program that coverts a number to the roman number representation. Make sure to use a single function that determines the units, tens, hundreds, and thousands digits.

Answer 1

Program:

#include <iostream>
using namespace std;
int ConvertNumToRoman(int number);   
int main()
{
int number;
cout<<"Enter number is:";
cin>>number;
ConvertNumToRoman(number);
return 0;
}
int ConvertNumToRoman(int number)
{
int num[] = {1,2,4,5,9,10,20,40,50,90,100,200,400,500,900,1000};
string Roman[] = {"I","II","IV","V","IX","X","XX","XL","L","XC","C","CC","CD","D","CM","M"};
int i=15;   
while(number>0)
{
int a = number/num[i];
number = number%num[i];
while(a--)
{
cout<<Roman[i];
}
i--;
}
}

output:

Enter number is:10   

X

Enter number is:100
