Classes and Drivers

Hello! I have written written my own class, which includes a header file and a .cpp file. I have also written the driver for this program. Everything looks fine to me, but I am receiving about 20 random errors. I will post my code for all 3 files but I believe it is a problem that can be diagnosed using just the driver.

The program is a bank account program that adds new accounts, withdraws, deposits, updates, displays, etc. Any help would be greatly appreciated! Thanks.

HEADER

#include <iostream>
#include <string>
using namespace std;
class BankAccount
{
public:
 BankAccount();
 void deposit( double amt );
 void withdraw( double amt );
 void update();
 int getID();
 void setID( int anID );
 double getBalance();
 void setBalance( double amt );
 double getInterestRate();
 void setInterestRate( double amt );
 string getFirstName();
 void setFirstName( string theName );
 string getLastName();
 void setLastName( string theName );
 string getFullName();
 void display();
private:
 string firstName, lastName;
 double interestRate;
 int ID;
 double balance;
};
