Answer on Question #81799 – Programming & Computer Science | C++

A bagel shop charges 75 cents per bagel for orders of less than a half-dozen bagels and 50 cents per bagel for orders of a half-dozen or more. Write a program that requests the number of bagels ordered and displays the price for each bagel and the total cost. Format the output results with two decimal places.

Answer:

#include <iostream>
#include <iomanip>
using namespace std;
// constants
const int HALF_DOZEN = 6;
const double PRICE = 0.75;
const double LOW_PRICE = 0.50;
int main()
{
    int number_of_bagels; // the number of bagels ordered
    double total_price;
    double price_per_bagel = PRICE;
    // read the input
    cout << "Enter the number of bagels ordered: ";
    cin >> number_of_bagels;
    // define the price per bagel
    if (number_of_bagels >= HALF_DOZEN) {
        price_per_bagel = LOW_PRICE;
    }
    // calculate the total price
    total_price = price_per_bagel * number_of_bagels;
    // output results
    cout << fixed << setprecision(2); // set output format for doubles with 2 decimal places
    cout << "Price for each bagel: " << price_per_bagel << endl;
    cout << "Total price: " << total_price << endl;
    return 0;
}
