Question

Demonstrate the ability to create and manipulate classes, data members, and member functions. This assignment also aims at creating a C++ project to handle multiple files (one header file and two .cpp files) at the same time.

Create a C++ project to do implement a simplified banking system.

Step 1:

Create a header file Bank.h to define a Bank class with the following members:

Data members: The program should implement data hiding, so please define data members accordingly.

- accountNumber

- balance

Note: The data types are not specified for this problem, so as to give you flexibility to design the program in your way.

Member functions: Please include only the declaration of the member functions in the header file. The implementation of member functions will later be done in the Bank.cpp file.

- Bank() constructor with no arguments to create a bank account with a default accountNumber as 9999 and balance value of zero.

- Bank(param1, param2) constructor with two parameters to create a bank account with a specified accountNumber and balance (as param1 and param2, respectively).

- withdraw(param1) function to withdraw a specified amount (param1) from the account. The function should first check if there is sufficient balance in the account. If the balance is sufficient, withdrawal is processed, otherwise display a message to the user that says
