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.

remove the semicolons from your function names

Code:

```double calc_payment(double Loan, double rate, int term); {     //your code }```
should be

Code:

```double calc_payment(double Loan, double rate, int term) {     //your code }```
correct
Code:

`void printTable(double payment, double Loan, double rate, int term);`
and
Code:

`void display();`

Code:

`Mortgage mtg(Loan, rate, term);`
^this one is right though since you're only declaring it
