Question

Assignment Draw a flowchart, using Microsoft Visio or LucidChart, to document the logic required to complete this program Save the flowchart as a PDF file Develop a C++ program, following the logic in your flowchart, to convert a series of whole number decimal values to their Roman equivalent. Develop a function that will accept a whole number value in the range 1-9999 and return a string containing the long-form Roman Numeral equivalent of the input value, consisting only of upper-case letters. The prototype for this function should be "string toLongRoman ( int x );". Develop a function that will accept any string and return a lower-case version of the same string. Do not limit this function to working only on Roman Numerals. The prototype for this function should be "string toLower ( string s);". Create a set of parallel arrays, each having 35 rows . . o A single-column array to contain whole numbers, and o Atwo-column array to contain Roman Numerals as strings. Convert a series of decimal values to Roman Numerals as follows: o Request a positive whole number in the range 1-5000 from the user. o Verify that the number is in the proper range. Reject all values outside this range and request a replacement value. Do no proceed until the user enters a valid number Starting with the user's input value, repeat the following steps until all 35 rows of both arrays are full Store the current numeric value into the next available row of the whole number array Using your first function, generate the upper-case long-form Roman Numeral equivalent of the current value Store the upper-case long-form Roman Numeral into the first column of the same row of the string array. For instance, if row 7 is the current row of the whole number array, then the upper-case Roman value string will be stored in row 7 of the first column of the string array o o o o o Using your second function, convert the upper-case Roman Numeral string to lower-case o Store the lower-case Roman Numeral string in the second column of the current row of the string array o Increment the current numeric value by one o Do not output anything until all values have been converted and al rays are full "Display the contents of the first 20 rows of all arrays, one set of values per row in neat columns on the console Save the contents of all 35 rows of all arrays, one set of values per row in neat columns to a file named "roman.txt" The format of the file output must be identical to that of the console output. Repeat this process of asking the user for a number and then converting a series of values to Roman Numerals . until the user enter enters a zero (since there is no Roman equivalent of zero)

Program.cpp

#include <iostream>

#include<fstream>
using namespace std;
int whole_xber_array[35];
string roman_array1[35],roman_array2[35];
  
string toLongRoman(int x){
    int decimal[] = {1000,900,500,400,100,90,50,40,10,9,5,4,1}; //base values
   const char *symbol[] = {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"}; //roman symbols
    int i = 0;
string s="";
    while(x){ //repeat process until x is not 0
        while(x/decimal[i]){ //first base value that divides x is largest base value
          s+=symbol[i];
            x -= decimal[i]; //subtract largest base value from x
        }
        i++;    //move to next base value to divide x
    }
    return s;
}


string toLower(string s){
transform(s.begin(),s.end(),s.begin(),::tolower);//convert string to lowercase
    return s;

int main()
