Thread: Error Problem

I've been working on this homework problem for a bit and I think I have it solved except I'm running into an error code

>Hw_3.obj : error LNK2019: unresolved external symbol "void __cdecl printTable(double,double,double,int)" (?printTable@@YAXNNNH@Z) referenced in function "void __cdecl process(void)" (?process@@YAXXZ)
1>Hw_3.obj : error LNK2019: unresolved external symbol "public: __thiscall Mortgage::Mortgage(double,double,int)" (??0Mortgage@@QAE@NNH@Z) referenced in function "void __cdecl process(void)" (?process@@YAXXZ)

It's referring to something in:

Code:

Mortgage mtg(Loan, rate, term);

double calc_payment(double Loan, double rate, int term);
{
	payment = Loan * term / (1 - pow(1 + rate, -term));
}


void printTable(double payment, double Loan, double rate, int term);
{
cout << setw(14) << "Interest" << setw(10) << "Principal" << endl;
	cout << setw(14) << "--------" << setw(10) << "---------" << endl;

	double	total_principal = 0;				// total of payments applied to principal
	double	total_interest = 0;				// total of payments applied to interest

	for (int i = 0; i < term; i++)				// print each payment
	{
		double to_interest = Loan * rate;		// periodic interest
		double to_principal = payment - to_interest;	// principal part of payment

		Loan -= (payment - to_interest);
		total_interest += to_interest;
		total_principal += to_principal;

		cout << setw(3) << i + 1 << ":" <<
			setw(10) << to_interest << setw(10) << to_principal << endl;
	}

	cout << endl << setw(14) << total_interest << setw(10) << total_principal << endl;

}
void display();
	cout << "Mortgage Summary : \n\n";
	cout << "Principal : " << Loan;
	cout << "\nAnnual Rate : " << rate << "%\n";
	cout << "Term : " << term << "\n";
	cout << "Monthly Payment : " << payment << "\n\n";

	printf("Do you want to print the payment table? (Y/N) ");
	cin >> resp;
	if ( resp[0] == 'Y' || resp[0] == 'y')
		printTable(payment, Loan, rate, term);
	else return;
}

And I have no idea how to fix it, any help or pointers would be appreciated.
