Question

C++

Model rocket engines (or motors) are generally purchases in boxes of 24 or packages of 3.

If I want 32 engines I would need to purchase 1 box of 24 and 3 packages of 3 (I would end up with 1 extra engine). Write a program that calculates how many boxes and packages you must purchase to get a specific number of engines. Also enter the price of a box and a package and calculate the total cost of the purchase. Use integer division (/, %) to calculate the number of boxes and packages. Note: when printing out the answer the correct word (box/boxes, package/packages) should appear after the number. If the number is 0, don't print anything at all.

Example Output:

Enter the number of engines needed: 30

Enter the cost of a box of 24 engines: 65.95

Enter the cost of a package of 3 engines: 8.49

You will need to purchase 1 box and 2 packages of engines

at a total cost of $82.93.

-----

Enter the number of engines needed: 10

Enter the cost of a box of 25 engines: 65.95

Enter the cost of a package of 3 engines: 8.49

You will need to purchase 4 packages of engines

at a total cost of $33.96.

Required Test Cases:

2, 65.95, 8.49

6, 65.95, 8.49

35, 65.95, 8.49

50, 65.95, 8.49

70, 65.95, 8.49

Requirements:

• Use the “Steps for creating a program” template to develop your solution.
• Declare and use at least one const variable (pi is an obvious choice, can you think of others?).
• Use meaningful variable names and reasonable data types.
• Include a comment section at the top of you file, with your name, the assignment number and a brief summary (in your own words) of what the program does.
• Include comments to describe the major sections of the program   
• Prompt for each input value you need and annotate the output to describe what it represents.

Answer 1

The c++ program with the given function and the test screenshots with formatted output are added.

#include <iostream>
using namespace std;

// Calculates how many boxes and packages you must purchase to get a specific number of engines.
// Also enter the price of a box and a package and calculate the total cost of the purchase.
int main()
{
float costOfBox, costOfPackage, totalCost;
int numberOfEngines, numberOfBoxes, numberOfPackages;
const float pi = 3.14;
// Enter the number of engines
cout << "Enter the number of engines needed: " << endl;
cin >> numberOfEngines;
  
// Enter the cost of a box
cout << "Enter the cost of a box of 24 engines: " << endl;
cin >> costOfBox;
  
// Enter the cost of package
cout << "Enter the cost of a package of 3 engines: " << endl;
cin >> costOfPackage;

// Calculate the number of boxes required, which is the quotient when divided by 24
numberOfBoxes = numberOfEngines/24;
  
// Calculate the number of packages required, which is the sum of quotient and remainder when divided by 3
if ((numberOfEngines % 24)%3 > 0) {
numberOfPackages = (numberOfEngines % 24)/3 + 1;
}
else {
numberOfPackages = (numberOfEngines % 24)/3;
}

// Compute the total cost of engines
totalCost = numberOfBoxes*costOfBox + numberOfPackages*costOfPackage;

// 9 conditional statements for correct format of string
if (numberOfBoxes == 0 && numberOfPackages == 0) {
cout << "You will need to purchase at a total cost of $0.00.";
}
else if (numberOfBoxes == 0 && numberOfPackages == 1) {
