Take any previous home assignment and modify it to save the output it shows on the screen to save to a file as well. For example, the BMR program, you could write out the person\'s calories per day to a file named BMR.txt You should ask them for the filename as shown below: count

Solution

// C++ code determine tax and the total cost for the item and save it to output file

#include <iostream>
#include <string.h>
#include <fstream>
#include <limits.h>
#include <stdlib.h>
#include <math.h>
#include <iomanip>

using namespace std;

int main ()
{
    string filename;
    cout << \"What is the filename to store to? \";
    cin >> filename;

    ofstream fin;
    fin.open(filename.c_str());
  
    if(!fin.is_open())
    {
        cout << \"could not open \" << filename << endl;
        return 0;
    }

    string ItemName;
    double unitPrice;
    double numberItemSold;
    double Subtotal;
    double tax;
    double shipping = 4.98;
    double total;

    cout << \"Enter Item name: \";
    cin >> ItemName;

    cout << \"Enter unit price: \";
    cin >> unitPrice;

    cout << \"Enter numbers of items sold: \";
    cin >> numberItemSold;

    Subtotal = unitPrice*numberItemSold;
    tax = Subtotal*8.25/100;
    total = Subtotal + tax + shipping;

    fin <<left<< setw(30) << \"Unit price: \" << unitPrice << endl;
    fin <<left<< setw(30) << \"Number of items sold: \" << numberItemSold << endl;
    fin <<left<< setw(30) << \"Subtotal: \" << Subtotal << endl;
    fin <<left<< setw(30) << \"tax: \" << tax << endl;
    fin <<left<< setw(30) << \"Shipping: \" << shipping << endl;
    fin << left<< setw(30) << \"Total: \" << total << endl;

    return 0;
}
