Store Program
May 2, 2011 at 2:27am UTC
I'm making a program where it first displays the food items in a .txt file. The user enters the food item name and amount of the food item. The program then outputs the total, tip (15% of total), and grand total (tip + total). I can't enter anything when I run the program.
1#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
string Item;
int Amount = 0;
double Total = 0;
double Price = 0.0;
double Tip = 0.0;
double GrandTotal = 0;
ifstream Read;
Read.open("Store.txt" , ios::in);
cout << "Store.txt" << endl;
cout << "Enter the item you want: " ;
getline(Read, Item);
for (int x = 0; x < 2; x++)
{
Read >> Amount >> Price;
Total = Total + (Amount * Price);
Tip = Total * .15;
GrandTotal = Total + Tip;
}
Read.close();
cout << "Your total is: $" << Total << endl;
cout << "Your tip is: $" << Tip << endl;
cout << "Yout grand total is: $" << GrandTotal << endl << endl;
cout << "Have a nice day!" << endl;
system("PAUSE" );
return 0;
}
Here is the .txt file:
1Cheeseburger 2.99
French Fries 1.99
Taco 2.50
Pizza 2.50
Salad 1.50
Thanks for helping.

Well, the problem is you never actually get any input from the user, only from a file (on line 20).

Well I updated it a little.
I need help for reading the things in the text file.
1#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
using namespace std;
int main()
{
string Item;
int Amount = 0;
char Another = ' ' ;
double Total = 0;
double Price = 0.0;
double Tip = 0.0;
double GrandTotal = 0;
char we;
ifstream Read;
Read.open("Store.txt" , ios::in);
cout << "MENU" << endl << endl;
for (int x = 0; x < 5; x++)
{
getline(Read, Item, '#' );
Read >> Price;
cout << Item << " $" << Price;
}
cout << endl << endl;
Another = 'y' ;
while (Another == 'y' )
{
cout << "Enter the item you want: " ;
getline(cin, Item);
cout << "Enter the amount of the item: " ;
cin >> Amount;
cout << "Do you want to order another item (y/n)? " ;
cin >> Another;
cin.ignore();
Total = Total + (Amount * Price);
Tip = Total * 0.15;
GrandTotal = Total + Tip;
}
cout << endl << endl;
Read.close();
cout << "Your total is: $" << Total << setprecision(5) << endl;
cout << "Your tip is: $" << Tip << setprecision(3) << endl;
cout << "Yout grand total is: $" << GrandTotal << setprecision(4) << endl << endl;
cout << "Have a nice day!" << endl;
system("PAUSE" );
return 0;
}

I would suggest making a function to load the contents of the file into variables. Use getline(file_object, string_name, char_deliminator) to load the item name. i.e.
1ifstream file;
string line;
file.open("file.txt" );
getline(file, line, ' ' ); //extracts chars into string until it hits a space
I think you can see where I'm going with this :)
EDIT:
maybe not, i just looked at your code more in depth
After you get the string from the file, run it through some conditionals
1if (line=="Cheeseburger" )
file >> CBcost; //integer variable
Just do the same for the rest of the variables. Also, you could use an array and an item# to reduce the amount of code (if statements), but that is a bit more complex.

I didn't really understand that. I can't get the program to read in the price of the item in the .txt file.

I kinda made an update. It will just end after I enter an item.
1#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
using namespace std;
int main()
{
string Item;
int Amount = 0;
char Another = ' ' ;
double Total = 0;
double Price = 0.0;
double Tip = 0.0;
double GrandTotal = 0;
ifstream Read;
Read.open("Store.txt" , ios::in);
cout << "MENU" << endl << endl;
for (int x = 0; x < 5; x++)
{
getline(Read, Item, '#' );
Read >> Price;
cout << Item << " $" << Price;
}
cout << endl << endl;
Another = 'y' ;
while (Another == 'y' )
{
cout << "Enter the item you want: " ;
getline(Read, Item);
Read >> Price;
cin.ignore();
cout << "Do you want to order another item (y/n)? " ;
cin >> Another;
Total = Total + (Amount * Price);
Tip = Total * 0.15;
GrandTotal = Total + Tip;
}
cout << endl << endl;
Read.close();
cout << "Your total is: $" << Total << setprecision(5) << endl;
cout << "Your tip is: $" << Tip << setprecision(3) << endl;
cout << "Yout grand total is: $" << GrandTotal << setprecision(4) << endl << endl;
cout << "Have a nice day!" << endl;
system("PAUSE" );
return 0;
}

My teacher told me to put in cin.ignore() somewhere after getline but I'm not sure where.
