Thread: Infinite Loop HELP!!

How can i get rid of the infinite loop in this program...

Code:

#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>
#include <iomanip.h>

int main()
{
	ifstream myFile;
	double accNum, gallons;
	char code;
	double totals, discount, gst, pst, finCost;
	myFile.open("gallons2.txt",ios::nocreate);
	
	if (myFile.fail())
	{
	cout<<"File cannot be opened"<<endl;
	exit(-1);
	}
	
	myFile>>accNum>>code>>gallons;
	
	while (!myFile.eof())
	{
		switch (code)
		{
		 case 'H':
		totals = (0.0005 * gallons) + 5;
			if ((totals > 75) && (totals < 1000))
				discount = totals * 0.1;
			else if (totals > 20)
				discount = totals * 0.05;
			else
				discount = 0;
		break;
		
		case 'C':
		totals = (0.00025 * (gallons - 4000000)) + 1000;
		discount = 0;
		break;
		
		case 'I':
		discount = 0;
		if (gallons <= 4000000)
			totals = 1000;	
		else if ((gallons > 4000000) && (gallons <= 10000000))
			totals = 2000;
		else
			totals = 3000;
		break;
		default:
		cout<<"Error Input";			
		break;
		}
		gst = (totals - discount) * 0.07;
		pst = (totals - discount) * 0.075;
		finCost = (totals - discount) + gst +pst;
		cout<<accNum<<code<<gallons<<totals<<discount<<gst<<pst<<finCost;
	}					
	
		
		cout<<"Account"<<endl;
		cout<<"Number  "<<"Code  "<<"Consumption  "<<"Total  "<<"Discount  "<<"GST  "<<"PST  "<<"Final Cost  "<<endl;
	myFile.close();
	return 0;
}

but still, the result is very very strange...

here is my cpp file and the txt file that the program need to open with...

and this is the txt file that the program required to open...

I'm not seeing any problems. And it compiled fine. I'm not a huge fan of your lack of white space in your output but I'm sure you didn't come here to be criticized.

Yeah,

now i am able to compile it and with the "setw" "setprecision" "setiosflags" i am able to make space between those number.

but i don't know why that my last result display 2 times. instead of once.
