Question

Write in C++.

The Bite-a Vite-a vitamin store needs an "expert" computer programmer to help keep track of their inventory. The store maintains all their vitamin stock information on disk. The data is organized as follows:

The first column contains the vitamin name (A, B, C, etc.)

The second column contains the unit price of a single jar of that particular vitamin.

The third column has the number of jars of that vitamin in the store.

For example:

Write a C++ program that will do the following:

1. Read data from the keyboard in the form

vitamin price quantity

2. Write and call a function that will return the total value of the store's inventory for that one vitamin product (unit_price * number_of_jars).

You will also calculate:

The average price of a vitamin

The total inventory (total number of jars)

Print the output so that it is organized as follows:

Vitamin Price Inventory Total Inventory

5. Write and call a function that will return the per unit price of a vitamin. The parameter to the function will include the vitamin name. (Hint use a vector or other container class).

--------------------------------------------------

The average price for a vitamin is: $9.98

The total store inventory is 104 jars of vitamins

Explanation / Answer

#include <iostream>
#include <cstdlib>
#include <iomanip>
#include <fstream>

double input (double, int);

using namespace std;

int
main()
{

float rate;
int frame;
int sum = 0, totalJars = 0;
float totalViteRate = 0;
ofstream outfile;

char vitmins;

ifstream infile;

infile.open("Totalinventory.txt");

if(infile.fail())
{
cerr << "file failed to open";
abort();
}

outfile.open("output.txt");

outfile << "Vitamin Price Inventory Total sumory " << endl;
outfile << "====================================================" << endl;
  

outfile << setprecision(2) << setiosflags (ios::fixed);
while (!infile.eof())
{
infile >> vitmins >> rate >> frame;
outfile << vitmins << setw(15) << rate << setw(15)
<< frame << setw(15) << input (rate, frame)<< endl;
sum ++;
totalJars += frame;
totalViteRate += rate;
}


outfile << " The average rate for a vitamin is : " << totalViteRate / sum << endl;
outfile << " The total store inventory is " << totalJars << " jars of vitamins" << endl;

infile.close();
outfile.close();


return 0;

}


double input (double t, int j)
{
return t * j;

}
