I need help in figuring out what to do for this program, it is a
program that reads book id, unit price, book purchased, book sold,
book returned, and city(respectively). It is a control break program
that prints a report for each city on a separate screen with a total,
then at the end it has a grand total. It prints to the screen and an
output file.
Input file looks like (the char is the city)
200 1.40 30 13 1 B
201 7.50 13 1 0 B
202 2.50 50 23 3 B
198 5.00 45 15 2 C
200 1.40 13 2 0 C
201 7.85 15 5 0 N
202 2.25 50 30 1 N
155 3.50 11 5 1 P
sample output
Store: Bloomington (which is all the ones with the letter B at the
end)
ID Price Purchase Sold Returns Inventory Value
200 1.40 30 13 1 25.20
201 7.50 13 1 0 90.72
202 2.50 50 23 3 76.35
Total: 93 37 4 192.27
then one for city C, N, and P
Then a grand total for all the citys put together
Here is what i got so far that is probably not close to working
#include <iostream>
#include <cctype>
#include <iomanip>
#include <fstream>
#include <cstdlib>
using namespace std;
void Header();
void ReadInput(istream& ins, int& id, double& unitPrice, int&
purchased, int& sold,
int& returned, char& city);
int main()
{
ifstream infile;
ofstream outfile;
infile.open("a:\\comics.txt");
if (infile.fail( )) {
cout << "Input file opening failed.\n";
system("pause");
exit(1);
}
outfile.open("a:\\inventory.txt");
if (outfile.fail( )) {
cout << "Output file opening failed.\n";
system("pause");
exit(1);
}
// format double on the screen to print with 2 decimals
cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(2);
// format doubles in the output file to print with 2 decimals
outfile.setf(ios::fixed);
outfile.setf(ios::showpoint);
outfile.precision(2);
int id, purchased, sold, returned;
double unitPrice;
int totalBooks = 0;
double invVal = 0;
char city;
int totalPurchased = 0, totalSold = 0, totalReturned = 0;
double totalInvVal = 0;
Header();
ReadInput(infile, id, unitPrice, purchased, sold, returned, city);
totalBooks = (purchased - sold + returned);
invVal = (unitPrice * totalBooks);
bool first = true;
int oldCity = 0;
while(infile >> id >> unitPrice >> purchased >> sold >> returned >>
city);
{
infile >> city;
//if (!first && oldCity != city)
{
switch(city)
{
case 'B':
cout << "Store: Bloomington";
break;
case 'N':
cout << "Store: Normal";
break;
case 'C':
cout << "Store: Champaign";
break;
case 'U':
cout << "Store: Urbana";
break;
case 'P':
cout << "Store: Peoria";
break;
}
cout << endl << endl;
totalPurchased += purchased;
totalSold += sold;
totalReturned += returned;
totalInvVal += invVal;
outfile << "ID\t" << "Price\t" << "Purchase " << "Sold " <<
"Returns "
<< "Inv. Value\n";
cout << "ID\t" << "Price\t" << "Purchase " << "Sold " <<
"Returns "
<< "Inv. Value\n";
outfile << id << "\t" << unitPrice << "\t" << purchased << "\t "
<< sold << "\t "
<< returned << "\t " << invVal;
cout << id << "\t" << unitPrice << "\t" << purchased << "\t " <<
sold << "\t "
<< returned << "\t " << invVal;
cout << endl << endl;
cout << "Totals\t\t" << totalPurchased << totalSold << totalReturned
<< totalInvVal;
}
first = false;
oldCity = city;
}
infile.close( );
outfile.close( );
cout << endl << endl;
system("pause");
return EXIT_SUCCESS;
}
void ReadInput(istream& ins, int& id, double& unitPrice, int&
purchased,
int& sold, int& returned, char& city)
{
ins >> id >> unitPrice >> purchased >> sold >> returned >> city;
}
void Header()
{
using namespace std;
cout << "\t\tCosmic Comics Inventory Report by Store\n";
cout << "\t\t Prepared by Daniel Buenger\n";
cout << "\t\t\t Date: Oct/30/2003\n\n";
}
Thanks in advance,
