    system ( "pause" );

Can't seem to find my error. Any suggestions?

[jorz]

what does it do and what doesn't ?

[jorz]

any errors?

[lwtan90]

AT line 10,

float const TAXRATE=0.20

AT line 14,

TAXRATE=0.30

You are contradicting yourself.

when something is constant, it is not supposed to be changed!

[LaC0saNostra]

The employee.txt input's an employees id, hourly rate and hours worked. I needed to change tax rates depending on their salary and I can't get the program to execute. It has something to do with line 14. Can't seem to figure it out

[lwtan90]

Depends on your platform and IDE,

line 28

system("PAUSE");

[LaC0saNostra]

Oh of course. So does line 10 just become float TAXRATE=0.20?

[lwtan90]

Yup. There is no need for it to be constant right? =)

[lwtan90]

Can you print out the error message?

[LaC0saNostra]

Got it to work thanks dude! Now I just need to declare a Martial Status by adding 5% to single person and deducting 5% to a head of household,
Declare marital status as a character: S=Single M=Married H=Head of Household is what I need to do.

My buddy gave me this hint:
char ms; if (ms=='s') taxrate=taxrate+0.05;
else if (........)

Where do you think the best place to put that staement is?

[lwtan90]

Actually anywhere you like, since it is addition, not multiplication.

[lwtan90]

It would be more elegant if you use a switch statement:

switch(ms)
{
   case 'S': taxrate+=0.05;
   break;
   case 'M': taxrate+=0.10;
   break;
   default: taxrate+=0.20;
}

[LaC0saNostra]

Now my question is because I've never used switch really. Between which lines am I inputting this statement? I'm gonna try inputting it in the right place till I get a reply back buddy

[LaC0saNostra]

Also because it is a symbol do i put char S, M; up at the top?

[lwtan90]

nope.

it should be stored in the employee.txt like the hourly rate, worked hours, etc.

and

it should be read from the file.

[LaC0saNostra]

I'm sorry for all of the questions but I'm totally new to programming.
2 Questions:

Here's my employee.txt:


8572 40 12.00
6423 40 15.00
7465 40 10.00
2477 40 16.00
5996 40 18.00

Where do I put it?

Also the statement:

switch(ms)
{
   case 'S': taxrate+=0.05;
   break;
   case 'M': taxrate+=0.10;
   break;
   default: taxrate+=0.20;
}

Goes exactly where? Then I should be good

[lwtan90]

employee.txt

8572 40 12.00 M
6423 40 15.00 S
...

I suggest that you put it right after the line 17 before you compute the taxamount.

=)

[LaC0saNostra]

Ok let me try that I'll get back to ya

[LaC0saNostra]

#include <iostream>
#include <fstream>
using namespace std;
int main () {
    ifstream input;// Declare file streams.
    input.open("employee.txt"); //Open the input file
        int numberofemployees;
        int employeeid, hoursworked;
        float hourlyrate, grosspay, taxamount, netpay;
        float TAXRATE=0.20;
        numberofemployees=0;
        while(input>>employeeid>>hoursworked>>hourlyrate) {
        grosspay=hoursworked*hourlyrate;
        if( grosspay > 1000 )    TAXRATE=0.30;
              else if( grosspay > 800 ) TAXRATE=0.20;
              else if( grosspay > 500 ) TAXRATE=0.10;
              else TAXRATE = 0.0;
              switch(ms)
{
   case 'S': taxrate+=0.05;
   break;
   case 'M': taxrate+=0.10;
   break;
   default: taxrate+=0.20;
}
        taxamount=grosspay*TAXRATE;
        netpay=grosspay-taxamount;
        cout<<"EMPLOYEE ID IS " << employeeid<<endl;
        cout<<"THE HOURS WORKED ARE " << hoursworked<<endl;
        cout<<"THE HOURLY RATE IS " << hourlyrate<<endl;
        cout<<"THE GROSSPAY IS " << grosspay<<endl;
        cout<<"THE TAXAMOUNT IS " << taxamount<<endl;
        cout<<"THE NETPAY IS " << netpay<<endl<<endl;
        }//WHILE
        input.close();//Close the files
    system ( "pause" );
}//main() 

That's what I have.

8572 40 12.00 M
6423 40 15.00 S
7465 40 10.00 M
2477 40 16.00 S
5996 40 18.00 M

That's what I have and it's not executing. Did I do something wrong?

[LaC0saNostra]

It states MS is undeclared
