Question

Need to revise the following code to use an array of product objects instead of two parallel arrays. The product class will need member variables to hold a product name and a quantity.

#include<iostream>

#include<string>

using namespace std;

int main()

{

//Declare variables

const int salsaTypes = 5;

const int jarsSold = 5;

string salsa[salsaTypes] = { "Mild", "Medium", "Sweet", "Hot", "Zesty" };

int jars[jarsSold];

int totalSales, highestSales, lowestSales;

string highestSoldProduct;

string lowesetSoldProduct;

//Repeat loop for all salsas

for (int i = 0; i < salsaTypes; i++)

{

//Ask user for the number of jars sold

cout << "Enter the number of jars sold for: " << salsa[i] << ": ";

cin >> jars[i];

}

//Initalize variables

totalSales = 0;

highestSales = jars[0];

highestSoldProduct = salsa[0];

lowestSales = jars[0];

lowesetSoldProduct = salsa[0];

//Repeat loop for all types of salsas

for (int i = 0; i < salsaTypes; i++)

{

//Calculate the total sales of the jars

totalSales += jars[i];

//Find the highest sales and product

if (highestSales < jars[i])

{

highestSales = jars[i];

highestSoldProduct = salsa[i];

}

//Find the lowest sales and product

if (lowestSales > jars[i])

{

lowestSales = jars[i];

lowesetSoldProduct = salsa[i];

}

}

//Display the details

cout << "Sales for each salsa type:" << endl;

for (int i = 0; i < salsaTypes; i++)

{

cout << "The number of jars sold for the salsa type:" << salsa[i] << " is " << jars[i] << endl;

}

//Display the total number of jars sold, highest amount and product, and lowest amount and product

cout << "The total number of jars sold in the past month:" << totalSales << endl;

cout << "The highest number of jars sold:" << highestSales << endl;

cout << "The higest selling product is:" << highestSoldProduct << endl;

cout << "The lowest number of jars sold:" << lowestSales << endl;

cout << "The lowest selling product is:" << lowesetSoldProduct << endl;

system("pause");

return 0;

}

CPP code:

#include<iostream>
#include<string>
using namespace std;

class Product
{
public:
string productName;
int quantity;
};

int main()
{
Product array[5];
array[0].productName="Mild";
array[1].productName="Medium";
array[2].productName="Sweet";
array[3].productName="Hot";
array[4].productName="Zesty";

const int salsaTypes = 5;
const int jarsSold = 5;

int totalSales, highestSales, lowestSales;
string highestSoldProduct;
string lowesetSoldProduct;

//Repeat loop for all salsas
for (int i = 0; i < salsaTypes; i++)
{
//Ask user for the number of jars sold
cout << "Enter the number of jars sold for: " << array[i].productName << ": ";
cin >> array[i].quantity;
}

//Initalize variables
totalSales = 0;
highestSales = array[0].quantity;
highestSoldProduct = array[0].productName;
lowestSales = array[0].quantity;
lowesetSoldProduct = array[0].productName;

//Repeat loop for all types of salsas
for (int i = 0; i < salsaTypes; i++)
{
//Calculate the total sales of the jars
totalSales += array[i].quantity;
//Find the highest sales and product
if (highestSales <array[i].quantity)
{
highestSales = array[i].quantity;
highestSoldProduct = array[i].productName;
}
//Find the lowest sales and product
if (lowestSales > array[i].quantity)
{
lowestSales = array[i].quantity;
lowesetSoldProduct = array[i].productName;
}
}
//Display the details
cout << "Sales for each salsa type:" << endl;

for (int i = 0; i < salsaTypes; i++)
{
cout << "The number of jars sold for the salsa type:" << array[i].productName << " is " << array[i].quantity << endl;
}

//Display the total number of jars sold, highest amount and product, and lowest amount and product
cout << "The total number of jars sold in the past month:" << totalSales << endl;
cout << "The highest number of jars sold:" << highestSales << endl;
cout << "The higest selling product is:" << highestSoldProduct << endl;
cout << "The lowest number of jars sold:" << lowestSales << endl;
cout << "The lowest selling product is:" << lowesetSoldProduct << endl;

return 0;
}

Screenshot of the code for better understanding(with comments):

SCreenshot of the code's output:

NOTE : I made the minimal changes possible so that my code doesn't have a significant deviation from yours.Hence, I have avoided the usage of private variables and member functions for those.
