Question

Write a C++ program that lets a maker of chips and salsa keep track of their sales for five

different types of salsa they produce: mild, medium, sweet, hot, and zesty. It should use

two parallel five-element arrays: an array of strings that holds the five salsa names and

an array of integers that holds the number of jars sold during the past month for each

salsa type. The salsa names should be stored using an initialization list at the time the

name array is created. The program should prompt the user to enter the number of jars

sold for each type. Once this sales data has been entered, the program should produce

a report that displays sales for each salsa type, total sales, and the names of the highest

selling and lowest selling products.

Note: Separate the files into three : Header.h , Functions.cpp, and Main.cpp

Code:

//Header.h

#ifndef HEADER_H

#define HEADER_H

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

class Salsa

private:

    string* salsaFlavours;

    int numOfFlavoursSold;

    int* soldCount;

public:

    Salsa(string* sf, int nsf);

    ~Salsa();

    void getSalesReport();

    void getTotalSales();

    void getHighestSelling();

    void getLowestSelling();

};

#endif

//Functions.cpp

    int i;

    for(i = 0; i < numOfFlavoursSold; i++)

    {

        salsaFlavours[i] = sf[i];

        total += soldCount[count];

    cout << endl << left << setw(40) << "Total Sales:" << right << setw(40) << total;

}

void Salsa::getHighestSelling()

{

    int count;

    int highest = soldCount[0];

    int index = 0;

    for (count = 0; count < numOfFlavoursSold; count++)

    {

        if (soldCount[count] > highest)

        {

        }

    }

    cout << endl << left << setw(40) << "Highest selling product:" << right << setw(40) << salsaFlavours[index];

}

void Salsa::getLowestSelling()

    int lowest = soldCount[0];

    int index = 0;

    for (count = 0; count < numOfFlavoursSold; count++)

}

//Main.cpp

#include <iostream>

#include <string>

#include <iomanip>

#include "Header.h"

using namespace std;

int main()

{

    const int NUM_FLAV = 5;

    string flavor[NUM_FLAV] = { "mild", "medium", "sweet", "hot", "zesty" };
