A while ago i had requested help for a Marital and Federal tax program. Unfortunately I'm making this program for a particularly picky person. So I ended up having to remake it somewhat. If someone could take a look and help me with this that'd be cool. Here's what I got:

FederalTaxHeader.h

#ifndef header_h
#define header_h


#include <iomanip>
#include <cmath>
#include <iostream>
#include <string>
#include <cctype>
#include <cstdlib>
#include <fstream>


using namespace std;

namespace Federal_Taxes
{
enum GrossType {LowGross, MedGross, HighGross};
}
using namespace Federal_Taxes;
	//List of the different functions
	
void extern displayRedo ();
char extern MaritalStatus(int Single, int Married);
void extern displayStatus (MaritalType GrossType);
void extern displaygross (int gross);
void extern displayInsuranceCheck ();

char extern getMaritalStatus (char & married);
{);
int extern getGross ();

char extern response ();

void extern askMaritalStatus ();
void extern displayUsage ();
void extern displayPurpose ();
char extern getAnswer ();

void extern myLabel ( const char * assignment, const char * date,
               ostream & out);
#endif

calc.cpp

#include "FederalTaxheader.h"

 //recieve sides from main, while useing the enum type declared in main
{

    GrossType gross; //declares shape under the enum type
    
    if (gross < 0)
     void displayRedo ()
{
	cout << "\n You have inputted an invalid entry" 
    "would you like to use this program again? Y/N ";

}
           	if (gross < 15001)
            gross = LowGross;
				
                else if (gross < 40001)
				gross = MedGross;
                
                else if (gross > 40000)
                gross = HighGross;
                }
   
	return GrossType;
}

Many thanks to whoever checks this out. If incase you can't remember what it is that I'm trying to accomplish, it says it in the output file. Thanks again

Does it not work or have you not fulfullied the persons needs?? and also i think it would be better if you give the problem again because some people would not have the time to look at your previous thread

The problem is that I am unsure as to what else I need to add to the program in order to make it comile. With that being said, If you look above I mentioned that you can see what the aim of the program is in the output.cpp file.

the errors that I get occur in the header.h file and they are:


C[Warning] `displayStatus' initialized and declared `extern'

24 variable or field `displayStatus' declared void

24 `MaritalType' was not declared in this scope

29 expected unqualified-id before '{' token

29 expected `,' or `;' before '{' token

>>C[Warning] `displayStatus' initialized and declared `extern'

In the header file you donot have any comma's where as in the file

display.cpp

you have two inputs for the function maybe that is the reason for that.

...
// [B]MaritalType[/B] is undefined at this point
void extern displayStatus (MaritalType GrossType);
...
{);  // <-- remove that one
int extern getGross ();

OK thanks for the peices of help guys. Now i'm still having some problems which i'll show u what they are. But in the meantime, here are the changes that i made to the certain files.

The problems that I am getting seem weird. I can't seem to figure out how to resolve them. Strangely enough, they all occur in main and here they are :

In function `int main()':

11 `response' cannot be used as a function

25 invalid conversion from `int' to `Federal_Taxes::GrossType'

28 invalid conversion from `int' to `Federal_Taxes::GrossType'

34 expected `(' before "married"

41 expected primary-expression before ')' token

your not closing your statements properly with the braces that is why your getting the "In function `int main()'" error
an example is this

{do
			{
				
				GrossType gross; 
                
				int Low_RATE; 
				int Med_RATE;
				int 
High_Rate;

change it to something like this

do
{
         GrossType gross; 
                
         int Low_RATE; 
         int Med_RATE;
         int High_Rate;

}//close your if statements

also, response is returning something so when your calling it you need to assign its value to a varible i.e

/*your variable*/=response();

i'm not sure at what point i'm supposed to close the loop cuz it seems no matter where i try to close it i get a ton more errors and i'm not sure what variable to put in front of response.

there are so many loops that are not closed and am afraid i cant tell you which one to close or which one to ommit as i dont know their individual use in your program....about the variable you can create your own or use one that needs to use the value passed from the function "response()" i.e

char ans=response(); //creating a new character variable and assign it to the value passed from response

then change your loop to something like this

do
{
     int getgross ();                                     
     gross = 0;				
     gross = getgross ();				
}while (ans == 'Y');

remove the first curly bracket just before the first "do"....you need to also format your code so that it looks readable
