need help

Your functions cannot "see" the variables declared in main().

So declare all the variables mentioned in the error report as globals (not recommended btw)

or create arguments for your functions and pass some of the variables in main() to them and declare some of the other variables inside the functions.

For example to fix this error...

payroll.cpp: In function ‘int outputScr()’:
payroll.cpp:77:13: error: ‘i’ was not declared in this scope


declare i as an int in the for loop in outputScr().

Move this code inside outputScr()...

        cout << "Payroll being written to file payroll.txt\n"; //output function
        outputFile.open("payroll.txt"); // output file
        if (outputFile.fail())
        {
           screenonly = true;
           cout <<" output file did not open\n";
           cout <<" output file will only be sent to the screen\n";
        }


and only declare screenonly and outputFile inside outputScr().

To the OP,

I can see exactly the same problems in your code that I, and others, told you how to fix in one of your previous threads.

If you're not going to pay attention to the answers that people here are giving to your questions, why should we waste our time giving you more answers?

Why? So you can ignore it like you usually do?

OK, let's give you one last chance to prove you're not a troll.

You need to read your compiler errors. They are there to help you. They tell you which line of code is causing the error, and what the nature of the error is. They are - sometimes - a bit hard to understand, but it is worth taking the time to try and understand them. You are clearly using Microsoft Visual Studio, which contains detailed help information about all the error and warning messages, so use the help system to get a better understanding.

Let's look at that first error:

payroll.cpp: In function ‘int regular()’:
payroll.cpp:137:26: error: assignment of function ‘int grossPay()’
payroll.cpp:137:26: error: cannot convert ‘double’ to ‘int()’ in assignment


It's telling you that problem is at line 137 of the file payroll.cpp, in the function regular. Let's look at that function:

1
2
3
4
5
6
 
int regular()
{
  double  hours, rate;
  if(hours <= 40)
      grossPay = hours * rate;
}


What is grossPay? You haven't defined any variable called grossPay in the function, so it must be some global symbol. Looking back through your code, we find:

int grossPay();

So grossPay is the name of a function! It's not a variable, so you can't assign a value to it as if it were a variable. If you want to store the result of hours * rate, you need to declare a variable to store it in.

Now, let's look at the next one:

payroll.cpp: In function ‘int overtime()’:
payroll.cpp:148:39: error: assignment of function ‘int overtime()’
payroll.cpp:148:39: error: cannot convert ‘double’ to ‘int()’ in assignment

It's almost exactly the same error, for exactly the same reason: you're trying to use the name of a function as if it were a variable, assigning a value to it.

Same problem, same solution.

And you're doing exactly the same thing in your grossPay function, too.

In all three of those functions, you also have another major error with your use of uninitialised variables, but you already had that explained to you days ago and you ignored it, so there's no point any of us wasting our time discussing it again.

i got it, so have to declare grossPay as variable in the function, for example double grossPay;
MikeyBoy (5631)
Well, that would make it legal C++, yes.

But why make your variable name the same as the name of a function? Why make things confusing by using the same name for different things? Make it clearer by using a different name altogether.
vin (300)
OP you need to study up on functions, how to pass information to them and how to use return to get a value from them.

Also in your original post you had brackets instead of parentheses for readData() but it didn't show as an error. How did you know to fix that?

int readData{string firstn[], string lastn[], string empID[],double hrs[], double rate[]};

Hi,
@vin
i'm not an expert at such things, but maybe the "overloaded function" error statement at line 31 and 32 of the compiler output are the result of that mistake.
Taking a look at this thing, it really looks simillar to a function that only consists of Var-decl.'s, although ";" seem to be missing.
Maybe the compiler ignores that, because of the error that is seen in the output (?)

Greets,
