Requirements:

$1.$ Create multiple C$++$ files $($put them in the same directory$/$folder$)$:

a$.$ Create a header file called $$expense$.$h$.$ This header file contains your

Expense class data definitions and method prototypes. $($Hint: Look at

BankAccount.h$).$ All data members must be declared as $$private$$ and provide

getter$/$setter methods to access them.

b$.$ Create a new CCP file called $$expense$.$cpp$$ to implement methods defined

your header file.

c$.$ Create a main program called $$main$-$expense.cpp$$ that displays the menu and

utilize your Expense $($Expense must implement these methods$)$ class to:

i$.$ Display description and amount

ii$.$ Determine if a substring is part of the description and return true or false

$2.$ The program must produce the same output as provided. The output should be

formatted nicely as given.

$3.$ The program must use array of Expense class. Hint: you must define a default

constructor in Expense.h to allow array declarations.

$4.$ The program must not use global variables. In another words, it must use local variables

and pass$-$by$-$value or pass$-$by$-$reference parameters.

$5.$ The program must define the maximum number of entries such as $100$ and keeps track

of the actual count of the current number of expenses entered by the user. You can also

utilize vector class to keep track of your expense objects.

$6.$ You should use data file to save or read from. At the beginning of your program, it reads

data from a data file named $$expenses$.$txt$$ and initialize your object array with this data.

Your program must check to see if the file exists or has data to read. Before your

program exits, it must save all expenses amount and descriptions into the data file.

$7.$ You must write at least $2$ functions in main$-$expense.cpp$.$

$8.$ You need to submit all header files, CPP files and data file $$expenses$.$txt$$

Required error handling:

The program MUST perform the following checks:

$1.$ Check for invalid amount $($negative or $0$ number$)$

$2.$ Description cannot be empty.

$3.$ Search is case$-$insensitive $($ignore case, but the user may type in any case$).$
