Question
This Application stores every transaction as soon as a transaction happens. Only amount of the transaction is stored, the date of transaction or any other data is not stored by this class.
When the application starts, it will ask the user about what is the maximum number of expected transactions. You will assume that the balance is zero when the program first starts.
The application will allow the user to make deposits as long as the balance is not above $100,000 FDIC limit.
The application will allow users to withdraw money as long as the withdrawal amount is no more than the available balance.
The application will allow the user to print the available balance at anytime.
The application will also allow the banker to print following statistics regarding the account at any time: balance total deposits total withdrawals average deposit amount average withdrawal amount minimum deposit amount minimum withdrawal amount maximum deposit amount maximum withdrawal amount variance of all the deposits variance of all the withdrawal standard deviation of all the deposits standard deviation of all the withdrawal This Application stores every transaction as soon as a transaction happens.

The data will be stored in that array.
Statistics Class [20 points] This class will provide functions that are shown in the UML class diagram shown below. Their functionalities are obvious from their names, but ask if you are not sure about any one.
The function add() adds a double value at the end of the array. The function get() obtains a copy of the value stored at the location i. The function set() overwrites (changes) the value stored at the location i by the provided value. The printStats() function invokes all other stats related functions and prints them on the screen.

Here are the functions in UML format so you can copy-n-paste add(value: double): void get(i: int): double set(i: int, data: double): void sum(): double average(): double min(): double max(): double var(): double stdev(): double printStats(): void
BankAccount Class [30 points] This class will have two instances of Statistics class. One will be used to store deposits and other one will be used to store withdrawals. This is different from how we implemented this class in the Midterm.

Implementation Notes For every class, all error conditions (in functions where errors can take place) must be identified and exceptions must be written and thrown. The exceptions must be “caught” only in the test() and process methods. [10 points]
For every class that you write, please implement a generic print() function [5 points] that prints all the data “owned” by that class directly or indirectly. Also implement static test() function that tests all other functions without any user input (all values that are otherwise expected from the user will be hard coded), and at least 5 new entries into the array.
Exceptions All Exception classes can be written inside a single file called “project1exceptions.hmyexceptions.h”. The constructors and functions of exception classes can be “inlined” like shown in the class. See lecture on Exceptions. Let us have a discussion about Exceptions here. Please list the exceptions that you feel must be there below (I will start with one):
NoDataException This exception will be thrown by a function in Statistics class that needs the size of the array to be greater than zero.
