Question

I need help modifying the following c++ code to use an array of Product Objects instead of two parrelle arrays. The product class wil need member variables to hold a propduct name and a quanititty.

Thank you

using namespace std;

//Function prototypes
int getSalesData(string[], int[]);
int posOfLargest(int[]);
int posOfSmallest(int[]);
void displayReport(string[], int[], int);

const int SIZE = 5;

int main()
{
   string name[SIZE] = { "mild ", "medium", "sweet ", "hot ", "zesty " };
   int sales[SIZE]; //holds jars sold for each salsa type

   int totalJarsSold = getSalesData(name, sales);

   displayReport(name, sales, totalJarsSold);
   system("pause");

   return 0;

}
