Question
Please use simple C++ commands and libraries. This is a beginning c++ class and I can't be using obscure libraries/algorithms/commands in my code.
Write a program that displays the roman numeral equivalent of any decimal number between 1 and 20 that the user enters. The roman numerals should be stored in an array of strings and the decimal number that the user enters should be used to locate the array elements holding the roman numeral equivalent. The program should have a loop that allows the user to continue entering numbers until an end sentinel of 0 is entered.

int posOfLargest(int [], int);
int posOfSmallest(int [], int);
int main()

string name[NUM_TYPES] =
{"mild ", "medium", "sweet ", "hot ", "zesty "};
int sales[NUM_TYPES]; // Holds jars sold for each salsa type
int totalJarsSold,
hiSalesProduct,
loSalesProduct;
for (int type = 0; type < NUM_TYPES; type++)
{
cout << "Jar sold last month of " << name[type] << ": ";

while (sales[type] < 0)
{ cout << "Jars sold must be 0 or more. Please re-enter: ";
