Question

Please I need help a sample code is provided below of the output

Description This project is an enhancement of your previous project using OOP concepts. You'lI define class and instantiate objects instead of using struct to implement your design Write a menu-driven program that provides the following options 1. Show All 2. Spend 3. Search expenses containing this string 4. Search expenses with greater than or equal to this amount 5. Exit It allows the user to select a menu option to display all expenses, add new entry, search for a substring and find the list of entries greater a given amount Requirements 1. Re-write your previous project with following new requirements a. Create a new header file called "expense.h". This header file contains your data definitions and method prototypes. 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 read the users input. The main program must call contain() method defined in Expense class to determine if the expense contains the target string 2. Your Expense class must provide the following methods a. string toString0: retum a string containing the expense description and amount. The main program calls this method to get back a description string to display b. bool contain(string target): retums true if the target string is contained in the expense description. Otherwise, it retums false. The search should be case-insensitive as in previous project 3. The program must produce the same output as provided. The output should be formatted nicely as given constructor to in Expense.h to allow array declarations variables and pass-by-value or pass-by-reference parameters track of the actual count of the current number of expenses entered by the user 4. The program must use array of Expense class. Hint: you must define a default 5. The program must not use global variables. In another words, it must use local 6. The program must define the maximum number of entries such as 100 and keeps 7. 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 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 8. You must write at least 2 functions in main-expense.cpp 9. You need to submit all header file, CPP file and data file "expenses.tt" 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 D:\>TrackExpensesUsingArray.exe Welcome to my expense tracker.
