For this we will be provided with a random integer. Our task is to convert the given number into its roman numeral equivalent.
Example
#include <bits/stdc++.h> using namespace std; //converting decimal to roman numeral int printRoman(int number){ int num[] = {1,4,5,9,10,40,50,90,100,400,500,900,1000}; string sym[] = {"I","IV","V","IX","X","XL","L","XC","C","CD","D","CM","M"}; int i=12; while(number>0){ int div = number/num[i]; number = number%num[i]; while(div--){ cout<<sym[i]; } i--; } } int main(){ int number = 3949; printRoman(number); return 0; }
Output
MMMCMXLIX
