writting data from structure in different function

Code:

data.cpp: In function `int WriteDatabase()':
data.cpp:58: `PersonInfo' undeclared (first use this function)
data.cpp:58: (Each undeclared identifier is reported only once
data.cpp:58: for each function it appears in.)

Those are the errors I am getting from this:

Code:

#include <iostream>
#include <string>
#include <fstream>
using namespace std;

int FillDatabase ( void );
int WriteDatabase ( );

struct Database
{
	string FirstName, LastName;
	int Age;
	string Marital;
	string Occupation;
};

int main ( void )
{  
	FillDatabase();
	WriteDatabase();
  	return 0;
}

int FillDatabase ( void )
{
	Database Person; 
	Database * PersonInfo;
	PersonInfo = &Person;

	cout<< "Name: ";
	cin>> Person.FirstName >> Person.LastName;

	cout<< "Age: ";
	cin>> Person.Age;

	cout<< "Marital Status: ";
	cin>> Person.Marital;

	cout<< "Occupation: ";
	cin>> Person.Occupation;

	return 0;
}

int WriteDatabase ( )
{
	fstream Log;
	Log.open("Data.txt", ios::app);
	
	if (Log == NULL)
	{
		cout <<"Open Error" <<endl;
		return 1;
	}

	Log <<"Name:" <<endl
	    <<PersonInfo->FirstName <<" " <<PersonInfo->LastName <<endl
	    <<"Age:" <<endl
	    <<PersonInfo->Age <<endl
	    <<"Marital Status:" <<endl
	    <<PersonInfo->Marital <<endl
	    <<"Occupation:" <<endl
	    <<PersonInfo->Occupation <<endl  <<endl;
	
	Log.close();
	return 0;
}

What am I missing?
I am trying to modularize this thing as much as possible, and while it's still in the stage of taking shape, I can't seem to figure out how to write the data from the structure in it's own function.

PersonInfo's scope is in FillDatabase, it doesn't exist in WriteDatabase. Either increase it's scope (make it global, ick), or pass it as a parameter to WriteDatabase.

Code:

// not tested, just quickly hacked up, likely not to work..
#include <iostream>
#include <string>
#include <fstream>
using namespace std;

struct Database
{
string FirstName, LastName;
int Age;
string Marital;
string Occupation;
};

int FillDatabase ( Database* PersonInfo );
int WriteDatabase ( Database* PersonInfo);

int main ( void )
{ 
Database PersonInfo;
FillDatabase(&PersonInfo);
WriteDatabase(&PersonInfo);
  return 0;
}

int FillDatabase ( Database* PersonInfo)
{
cout<< "Name: ";
cin>> PersonInfo->FirstName >> PersonInfo->LastName;

cout<< "Age: ";
cin>> PersonInfo->Age;

cout<< "Marital Status: ";
cin>> PersonInfo->Marital;

cout<< "Occupation: ";
cin>> PersonInfo->Occupation;

return 0;
}

int WriteDatabase (Database* PersonInfo)
{
fstream Log;
Log.open("Data.txt", ios::app);

if (Log == NULL)
{
cout <<"Open Error" <<endl;
return 1;
}

Log <<"Name:" <<endl
    <<PersonInfo->FirstName <<" " <<PersonInfo->LastName <<endl
    <<"Age:" <<endl
    <<PersonInfo->Age <<endl
    <<"Marital Status:" <<endl
    <<PersonInfo->Marital <<endl
    <<"Occupation:" <<endl
    <<PersonInfo->Occupation <<endl  <<endl;

Log.close();
return 0;
}

See, I have pm'ed, instant messaged, emailed, and talked with skilled friends about this problem.
They told me global or scope increase.
I couldn't find anything about this.

I'll just shape it around a bit, start to add in the error checking I planned on after this problem was solved, and I'm set.

Thanks a ton SilentStrike.
(your code did work btw)
