Little help please

Here is what I'm working on:

Write and test two functions enterData() and printCheck() to produce the sample paycheck illustrated in Figure 7-21 on the screen (not including the boxed outline). The items in parenthese should be accepted by enterData() and passed to printCheck() for display.

Here is what I have so far. The display from printCheck() is way off and I can fix that later, so don't worry about that. But what else is wrong here?

Code:

#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	void enterData();
	void printCheck(int, int, int, char, char, double);

	enterData();

	return 0;
}

void enterData()
{
	int month, day, year;
	char firstName, lastName;
	double amount;

	cout << "Enter the month number: ";
	cin >> month;
	cout << "Enter the day: ";
	cin >> day;
	cout << "Enter the year: ";
	cin >> year;

	cout << "Enter first name of the person getting paid: ";
	cin >> firstName;
	cout << "Enter the last name of the person getting paid: ";
	cin >> lastName;

	cout << "Enter the amount being paid: ";
	cin >> amount;

	printCheck(month, day, year, firstName, lastName, amount);

	return;
}

void printCheck(int mm, int dd, int yy, char first, char last, double money);
{
	cout << setw(40) << fixed << "Zzyz Corp." << setw(20) << "Date: "
		<< mm << "/" << dd << "/" << yy << "\n"
		<< setw(40) << "1164 Sunrise Avenue\n"
		<< setw(40) << "Kalispell, Montana\n\n"
		<< setw(40) << "Pay to the order of: " << first << " " << last
		<< setw(20) << "$" << money << "\n\n"
		<< "UnderSecurity Bank\n"
		<< setw(40) << "Missoula, MT" << setw(20) << "____________________\n"
		<< setw(40) << "Authorized Signature";

	return;
}

Put prototypes at the beginning of the source file.
Char holds a single character, not a string. Use std::string.
Cin >> just reads to the first whitespace, so use std::getline if you need to read spaces and tabs and such. Just a heads up.

What is a prototype? I changed the code to use strings instead of chars and getline() instead of cin. I am still getting these 3 errors:

error C3861: 'printCheck': identifier not found, even with argument-dependent lookup line 47

error C2365: 'printCheck' : redefinition; previous definition was a 'formerly unknown identifier' line 52

error C2447: '{' : missing function header (old-style formal list?) line 53

GIYF

Code:

void printCheck(int mm, int dd, int yy, char first, char last, double money); //<-- remove
