Question

n 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.

Instructions

1. Study the prewritten code to make sure you understand it.
2. Write the code that searches the array for the name of the add-in ordered by the customer.
3. 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.

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

   Cream

   Caramel

   Whiskey

   chocolate

   Chocolate

   Cinnamon

   Vanilla

GIVEN CODE

// JumpinJava.cpp - This program looks up and prints the names and prices of coffee orders.  

// Input:  Interactive

// Output:  Name and price of coffee orders or error message if add-in is not found

#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[] = {"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.

   return 0;

} // End of main()

Answer 1

#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[] = {"Cream", "Cinnamon", "Chocolate", "Amaretto", "Whiskey"};
  
// Initialized array of add-in prices
  
double addInPrices[] = {.89, .25, .59, 1.50, 1.75};
  
int x; // Loop control variable
double orderTotal = 2.00; // All orders start with a 2.00 charge
  
double total=0;
  
while(addIn!="XXX"){// loop till XXX is not entered
bool foundIt = false; // Flag variable
// Get user input
cout << "Enter coffee add-in or XXX to quit: ";
cin >> addIn;
if(addIn=="XXX"){// if XXX is entered then break
break;
}
for(x=0;x<NUM_ITEMS;x++){// traverse the array
if(addIns[x]==addIn){// if add-in found in array
cout<<"Name of coffee add-in: "<<addIn<<", price: "<<addInPrices[x]<<endl;// print name,price
foundIt=true;
total+=addInPrices[x];// add cost of add-in to total order
break;
}
}
if(foundIt==false){// if add-in not found
cout<<"Sorry, we do not carry that."<<endl;
}
}

cout<<"Cost of total order: "<<total; // print cost of total order
  
return 0;

} // End of main()
