C++ :: Employee Database - Bizarre Error With If Statement

I have written a program that stores employees in a database object. You can Add, hire, fire, promote, demote, and display employees. The program uses an interface, a database class, and an employee class with member functions.

The strange behavior is in my switch statement in interface.cpp. I have a '#' that represents a command line. Add and Display functions are ok, but if I hire, fire, promote or demote. It will display '##' for the next input. I ran the debugger and after hire/fire/promote/demote is called, the first if-statement goes to 'else' and I'm trying to figure out why.

Note: main() calls mainMenu() to run the program

// interface.cpp
#include <iostream>
#include "database.h"
#include "display.h"
void mainMenu() {
displayMenu();
Database* employeeDatabase = new Database();

[Code] .....

Here are the two classes...

// database.cpp
#include <iostream>
#include <vector>
#include <memory>
#include "employee.h"
#include "database.h"
using namespace std;
