Validating parallel arrays

  arrays, c++

I am working on this assignment for my C++ programming class and have come to a standstill. I would like some suggestions as to what I need to fix to get this correct. The directions are as follows:


In this lab, you use what you have learned about parallel arrays to complete a partially completed C++ program. The program should:

  • Either print the name and price for a coffee add-in from the Jumpin’ Jive Coffee Shop
  • Or it should print the message Sorry, we do not carry that.

Read the problem description carefully before you begin. The file provided for this lab includes the necessary variable declarations and input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints the error message if the add-in is not found. Comments in the code tell you where to write your statements.


  • Study the prewritten code to make sure you understand it.

  • Write the code that searches the array for the name of the add-in ordered by the customer.

  • Write the code that prints the name and price of the add-in or the error message, and then write the code that prints the cost of the total order.

  • Execute the program by clicking the Run button at the bottom of the screen. Use the following data:


Here is the code I have so far:

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

int main()
   // Declare variables.
   string addIn;     // Add-in ordered
   const int NUM_ITEMS = 5; // Named constant
   // Initialized array of add-ins
   string addIns[NUM_ITEMS] = {"Cream", "Cinnamon", "Chocolate", "Amaretto", "Whiskey"}; 
   // Initialized array of add-in prices
   double addInPrices[] = {.89, .25, .59, 1.50, 1.75};
   bool foundIt = false;     // Flag variable
   int x;                // Loop control variable
   double orderTotal = 2.00; // All orders start with a 2.00 charge

   // Get user input
   cout << "Enter coffee add-in or XXX to quit: ";
   cin >> addIn;
   // Write the rest of the program here. 
        foundIt = false;
        x = 0;
        while(x < 1){
            if (addIn == addIns[x]){
                foundIt = true;
                orderTotal = addInPrices[x];
            x += 1;
        if(foundIt == true){
            cout << "The price of" << addIns[x] << "is" << addInPrices[x] << "." << endl;
            cout << "Sorry, we do not carry that." << endl;
   return 0;
} // End of main()
