reading in from files

im reading in from a txt file that looks like this:
4 6.75 120 4444
1 1200.00 1111
3 10000.00 3333
2 12.50 50 2222
-1

and bassically im trying to just read in one number at a time however im getting an infinite loop . im using a switch statement that is suppose to stop not at the end of file but when it comes to a -1
anyways heres the code any hep would be much apreicated

Code:

#include <iostream>
#include "pay.h"
#include <iomanip>
#include <string>
#include <fstream>
using namespace std;

int main()
{  //start declarations
	pay p;
	string empnum;
	int week=0;
	int hour=0;
	int pie=0;
	char paycode;
	double hoursal;
	double comtotal;
	double pricepie;
	string inloc;
	string outloc;
	ofstream output;
	ifstream input;
	// end declarations

	output<<fixed<<showpoint<<setprecision(2); //sets everything to two decimal points
	cout<<"Where is the input file"<<endl; // takes in the inputfile location
	getline(cin,inloc);
	input.open(inloc.c_str(), ios::out);
	cout<<"Where would you like the output file to be saved"<<endl;// asks where to save the output file
	getline(cin,outloc);
	output.open(outloc.c_str(), ios::out);
	output<<setw(10)<<"WEEKLY PAY REPORT FOR THE WIDGET COMPANY"<<endl; //the heading for the ouput file starts here
	output<<endl;
	output<<"EMPLOYEE"<<setw(5)<<"WEEKLY"<<setw(5)<<"HOURLY"<<setw(5)<<"HOURS"<<setw(5)<<
		"GROSS"<<setw(5)<<"PRICE"<<setw(5)<<"NUMBER OF"<<endl;
	output<<"NUMBER"<<setw(5)<<"PAY"<<setw(5)<<"SALARY"<<setw(5)<<"WORKED"<<setw(5)<<
		"SALES"<<setw(5)<<"PER PIECE"<<setw(5)<<"PIECES"<<endl; //the heading for the output file ends here
	do
	{
		
		input>>paycode; // takes in the paycode from the file
		switch(paycode) //all the computations done here calculating total payroll and the payment for each employee
		{
			case '1':input>>week;input>>empnum;p.weeklyPay(week);
				output<<empnum<<setw(5)<<week;break;
			case '2':input>>hoursal;input>>hour;input>>empnum;p.hourlyPay(hour,hoursal);
				output<<empnum<<setw(5)<<p.hourlyPay(hour,hoursal)<<setw(5)<<hoursal<<setw(5)<<hour;break;
			case '3':input>>comtotal;input>>empnum;p.commissionPay(comtotal);
				output<<empnum<<setw(5)<<p.commissionPay(comtotal)<<setw(10)<<comtotal;break;
			case '4':input>>pricepie;input>>pie;input>>empnum;p.piecePay(pricepie,pie);
				output<<empnum<<setw(5)<<p.piecePay(pricepie,pie)<<setw(20)<<pricepie<<setw(5)<<pie;break;
			case '-1':input.close();break; // close the input file when its -1
		}
	//	p.getPayRollAmount(); //running total of the payroll updates every round the loop runs
	}while(paycode !='-1'); //condition for the loop to keep running

	output<<endl; //the rest of the output file starts here
	//output<<"Total payroll: $"<<p.getPayRollAmount()<<endl;
	output<<"Total number of managers paid: "<<p.getWeekly()<<endl;
	output<<"Total number of hourly workers paid: "<<p.getHourly()<<endl;
	output<<"Total number of commission works paid: "<<p.getCommission()<<endl;
	output<<"Total number of piece workers paid: "<<p.getPiece()<<endl;
	output<<endl;
	output<<"Programmer: Johnny Gaffey"; // the last of the outputfile ends here
	output.close(); //close the output file
	cout<<endl<<"Processing complete";
	return 0;
}//main

this is what the output is suppose to look like:

WEEKY PAY REPORT FOR THE WIDGET COMPANY

EMPLOYEE WEEKLY HOURLY HOURS GROSS PRICE # OF
NUMBER PAY SALARY WORKED SALES PER PIECE PIECES
4444 810.00 6.75 120
1111 1200.00
3333 820.00 10000.00
2222 687.50 12.50 50


total payroll: $3517.50
total number of managers paid: 1
total number of hourly workers paid: 1
total number of commission workers paid: 1
total number of piece workers paid: 1

1. Well, first of all. When reading in from a file it's generally better practice to do something like while(in_file.good()), or while(s<<in_file), rather than looking for your own sentinel value.

2. It's easier to read when you spread things out a bit more.

3. A char can only hold a single character, so something like "-1" needs either a character array or string.

Code:

char paycode;

do
{
    input>>paycode;
    switch(paycode)
    {
    case '1':
        input>>week;
        input>>empnum;
        p.weeklyPay(week);
        output<<empnum<<setw(5)<<week;
        break;
    case '2':
        input>>hoursal;
        input>>hour;
        input>>empnum;
        p.hourlyPay(hour,hoursal);
        output << empnum << setw(5) << p.hourlyPay(hour,hoursal)                                               
               << setw(5) << hoursal << setw(5) << hour;
        break;
    case '3':
        input>>comtotal;
        input>>empnum;
        p.commissionPay(comtotal);
	output << empnum << setw(5) << p.commissionPay(comtotal) 
               << setw(10) << comtotal;
        break;
    case '4':
        input >> pricepie;
        input>>pie;
        input>>empnum;
        p.piecePay(pricepie,pie);
        output << empnum << setw(5) << p.piecePay(pricepie,pie) << setw(20)
               << pricepie << setw(5) << pie;
        break;
    case '-1':
        input.close();
        break; // close the input file when its -1
}
//	p.getPayRollAmount(); //running total of the payroll updates every round the loop runs
}while(paycode !='-1'); //condition for the loop to keep running

You want to be reading numbers (i.e. int) and not char because paycode can't ever be equal to '-1' since '-1' is not a character. So, make paycode an int and get rid of all those single quotes in your switch statement.

I also have no idea why you are calling some of those functions (in blue) twice with the same arguments.

thanks for the quick responses and as for the functions being called twice... the function returns a number andim calling it the 2nd time just to print that number

also after trying that advice i changed paycode to an int and took off the ' ' but now this is as far as it gets:

WEEKLY PAY REPORT FOR THE WIDGET COMPANY

EMPLOYEEWEEKLYHOURLYHOURSGROSSPRICENUMBER OF
NUMBER PAYSALARYWORKEDSALESPER PIECEPIECES

also doesnt seem like the setw(5) is working any ideas?

as for the functions being called twice... the function returns a number andim calling it the 2nd time just to print that number

The question is: why are you calling the function the 1st time?

also doesnt seem like the setw(5) is working any ideas?

If you have a heading like "HOWLONGDOYOUTHINKTHISHEADINGIS", and you use setwidth(5), what are you trying to accomplish?

Code:

input.open(inloc.c_str(), ios::out);

Do you know what ios::out means?

You need to learn how to format a switch statement. Look in your book or look up a tutorial. Your code is a mess.

Since you haven't posted your class, as far as anyone knows, no data is saved in your member variables.

calling the function the first time updates the total number of employees of that kind and calculates the weekly salary

the setw(5) was suppose to creat a space inbetween the text

yea i know what iosut meansi was copy and pasting code from my last project and forgot to take out that part from the in part.

as for the switch sorry its so messy i put some spacing in to make it more readable

would it help if i post my class?

update: the output isnt reading the employee number 1111 for some reason and no spacing in the output... setw() doesnt seem to be working for me maybe i did something wrong

and at the bottem where it says how many of each kind of employee i have managers is 1 like it should be but the others are:
Total number of managers paid: 1
Total number of hourly workers paid: 4244878
Total number of commission works paid: -479997245
Total number of piece workers paid: 3359306
