C++ Check Book Program

I need to have a checkbook program that uses the following items. My code that I have appears below.

1) Math operations using built-in math functions

2) Class type in a separate .h file with member functions (accessor functions, get, set, show, display find, etc). There needs to be an overloaded function base/derived classes or a template.

3) Binary File

#include <iostream>

        cout<<"Enter 2 to deposit cash\n";
        cout<<"Enter 3 to transfer from/to savings account\n";
