You need to explain what problem you have with this code. Also it should be

[code=cplusplus]

Re: Any help with C++ payroll! -noob

It would be good if you could tell us what problems you're facing. So i'm presuming that employee.txt is an infile? Please upload it.

const float TAXRATE=0.10;
ifstream fin("C:\Dev-Cpp\employee.txt");

while (!fin.eof()){
fin >> employeeid >> hoursworked >> hourlyrate;
cout<<"EMPLOYEE ID IS: "<<employeeid<<endl;
cout<<"THE HOURS WORKED ARE: "<<hoursworked<<endl;
cout<<"THE HOURLY RATE IS: "<<hourlyrate<<endl;
grosspay=hoursworked*hourlyrate;
taxamount=grosspay*TAXRATE;
netpay=grosspay-taxamount;
cout<<"THE GROSSPAY IS"<<grosspay<<endl;
cout<<"THE TAX AMOUNT IS"<<taxamount<<endl;
cout<<"THE NETPAY IS"<<netpay<<endl;

Re: Any help with C++ payroll! -noob

You need a [/code] at the end of your statements.

refer to what ithelp said above. You need to escape your \ inside the quotes, so your file name string probably needs to be "C:\\Dev-Cpp\\employee.txt"

Also it is better to explicitly state the mode in which you want to open the file, and then check if the file pointer is valid or not before proceeding to try and read the contents of your file.

(Toggle Plain Text)

ifstream ifs ( "test.txt" , ifstream::in );

if(ifs.good()) { // we have a valid pointer, proceed

}

Re: Any help with C++ payroll! -noob

Hey, Are you sure that the file is being opened?
Because Your Code Doesnt Test whether it has opened it

C++ Syntax (Toggle Plain Text)
if (myfile.is_open()) { /* ok, proceed with output */ }
if (myfile.is_open()) { /* ok, proceed with output */ }

You should have an if statement like the above to know that you have opened the file successfully.
