Question

NOTE: All C++ programs that you write must have comments at the top with the program name, your name, and the pseudocode describing what the program will do.

1. Create a new program that will calculate the total cost for software purchased from a store. Each software package costs $99.00, but discounts are given on the total cost, based on the number of packages purchased.

a. Ask the user for the number of packages they want to buy

b. Calculate the total price, using the discount based on the table below.

c. Print the number of packages and total cost with labels.

Quantity​ ​Discount

10-19​​​ 20%

20-49​​​ 30%

50-99​​​ 40%

100 or more​​ 50%

comment: Please use a C++ compiler, also the using namespace std; to run the program. Thank you

Answer 1

Program:

// totalCost.cpp

// this program will calculate the total price, using the discount given in the question

// declare variable numberOfPackages

// declare variable totalPrice, discount

// get the value of numberOfPackages from user

// then, set the value of discount

//     if (numberOfPackages >= 10 && numberOfPackages <= 19)

//     {

//         discount = 20.0;

//     }

//     else if (numberOfPackages >= 20 && numberOfPackages <= 49)

//     {

//         discount = 30.0;

//     }

//     else if (numberOfPackages >= 50 && numberOfPackages <= 99)

//     {

//         discount = 40.0;

//     }

//     else if (numberOfPackages >= 100)

//     {

//         discount = 50.0;

//     }

// totalPrice = numberOfPackages * (99.0 - ((discount / 100) * 99.0))

// print numberOfPackages, totalPrice

#include <iostream>

using namespace std;

int main()

{

    int numberOfPackages;        // declare variable numberOfPackages

    double totalPrice, discount; // declare variable totalPrice, discount

    // Ask the user for the number of packages they want to buy

    cout << "Enter the number of Packages you want to buy: ";

    cin >> numberOfPackages;

    // set the value of discount variable as per the table

    if (numberOfPackages >= 10 && numberOfPackages <= 19)

    {

        discount = 20.0;

    }

    else if (numberOfPackages >= 20 && numberOfPackages <= 49)

    {

        discount = 30.0;

    }

    else if (numberOfPackages >= 50 && numberOfPackages <= 99)

    {

        discount = 40.0;

    }

    else if (numberOfPackages >= 100)

    {

        discount = 50.0;

    }

    // calculate the total price, using the discount given in the question

    totalPrice = numberOfPackages * (99.0 - ((discount / 100) * 99.0));

    // Print the number of packages and total cost with labels

    cout << "Number of packages: " << numberOfPackages << endl;

    cout << "Total Cost: " << totalPrice;

    return 0; // return 0

}
