# Roman Numeral Generator

Hello all! So as you can read in some previous posts I have been working on a roman numeral ID method for my Simpossible game. The code is now finished! Previous posts were only inclusive up to the roman numeral for 20 but now it is complete, including numerals all the way up to 100! It took a while to perfect the method, but ALAS it is complete! I had lots of fun with this specific method as it posed some very interesting challenges utilizing the modulus operation. Ill paste the code and some output below! Enjoy!

``````    // Difficulty above 6

// Creates string for as many times as 50 goes into the number
for(int rep = 0; rep < (randomNum/50); rep++){

// Adds L to the string
number += "L";

// If the repetition is 1, the string will be cleared and "C" will be put instead
if(rep == 1){
number.clear();
number += "C";
}
