Question

Program 2 <100 points>: Chips and Salsa (chipsSalsa.cpp) Write a program that lets a maker of chips and salsa keep track of sales for five different types of salsa: mild, medium, sweet, hot, and zesty. The program should use two parallel 5-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 (using {}) 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. You need to create the following functions in addition to main. fillJarsSoldArray - prompts the user to enter the number of jars sold for each type and fills the jars sold array. You must use a loop here. printSales - displays sales for each salsa type. getTotal - returns the total sales. Display the total in main. getHighest Lowest Selling - returns the indices of the highest and lowest selling salsas. Do not pass the name array to this function. Display the highest and lowest selling types in main. Input Validation: Do not accept negative valu for number of jars sold. You must use getInt() in input.h. Your prompts and output format have to be exactly the same as the sample run below. Test your program using the following test case [kslott@empress cs111_lec spr11]$ ./a.out rejected by getInt() in input.h Enter the number of jars sold for mild: -1 Invalid. Enter a number between 0 and 1000000: 1000001 Invalid. Enter a number between 0 and 1000000: 100

Program code to copy:

// ---------------------------------------------- chipsSalsa.cpp ---------------------------------------------- //

#include<iostream>
#include<iomanip>
using namespace std;
  
// --- Two Parallel Arrays -> (One for Salsa names) & (One for number of jars sold for each Salsa) --> Making them Global

// --- Initializing salsaNames array
string salsaNames[] = {"mild", "medium", "sweet", "hot", "zesty"};
int jarsSold[5];

// --- A function to prompt the user to enter number of jars sold for each type & fills the jars as specified in statement
void fillJarsSoldArray(){
  
   // --- Using a for loop to enter values
  
   for(int i=0; i<5; i++){
      
       cout<<"\nEnter the number of jars sold for "<<salsaNames[i]<<": ";
       cin>>jarsSold[i];
      
       // --- Then check for negative value & continue prompting unitl user enters positive value
       // --- Then as getInt() determines that it cannot go above 1000000, so also implyinng getInt() condition
       while(jarsSold[i] < 0 || jarsSold[i] > 1000000){
          
           cout<<"\tInvalid. Enter a number between 0 and 1000000: ";
           cin>>jarsSold[i];  
       }
   }
}

// --- A function to print Sales for each Salsa type

void printSales(){
  
   // --- printing according to given format
   cout<<"\n\n";
   for(int i=0; i<5; i++){
      
       cout<<left<<setw(10)<<salsaNames[i]<<right<<setw(10)<<jarsSold[i]<<endl;
   }
}

// --- A function that will calculate & return total sales

int getTotal(){
  
   int totalSales = 0;   // --- A variable for storing total sales
  
   for(int i=0; i<5; i++){  
       totalSales += jarsSold[i];   // --- With each iteration, adding jars for each salsa
   }
  
   return totalSales;
}

// --- A function that determines the indices of highest & lowest selling salsas

void getHighestLowestSelling(int * highest, int * lowest){
  
   // --- Variables to store highest & lowest assign 0 to highest & assume first index value is minimum
  
   int highestSales = 0, lowestSales = jarsSold[0];
  
   // --- Then further iterating array to get Highest & lowest sales
  
   for(int i=0; i<5; i++){
      
       if(jarsSold[i] > highestSales){
           highestSales = jarsSold[i];
           *highest = i;
       }
      
       if(jarsSold[i] < lowestSales){
           lowestSales = jarsSold[i];
           *lowest = i;
       }
   }
}

int main(){

   // --- Filling number of jars sold (soldarray) by calling function fillJarsSoldArray
  
   fillJarsSoldArray();

   // --- display sales for each salsa type by calling function printSales
  
   printSales();  
  
   // --- displaying total sales by calling functions getTotal
  
   cout<<"\nThe total number of jars sold is "<<getTotal()<<endl;
  
   // --- Two variables to determine highest & lowest sales
  
   int highest = 0 , lowest = 0;
  
   // --- Passing these to function getHighestLowestSelling because as specified we have to return indices of both
   // --- highest & lowest sales, we cannot return two values, so we will pass these values by reference
  
   getHighestLowestSelling(&highest, &lowest);
  
   // --- print highest & lowest selling type
  
   cout<<"The highest selling type is "<<salsaNames[highest]<<endl;
   cout<<"The lowest selling type is "<<salsaNames[lowest]<<endl;
  
}

Sample output:

Enter the number of jars sold for mild: -1 Invalid. Enter a number between 0 and 1000000: 1000001 Invalid. Enter a number between 0 and 1000000: 100 Enter the number of jars sold for medium: 500 Enter the number of jars sold for sweet: 0 Enter the number of jars sold for hot: 250 Enter the number of jars sold for zesty: 1000 100 mild medium 500 sweet hot 250 zesty The total number of jars sold is 1850 The highest selling type is zesty The lowest selling type is sweet 1000
