Question

I need help writing this code in C++ and I’m using xcode for mac

the objective is in the first picture and the rest is a sample output of the code thaf needs to be similar

bjectives: . Perform C++ string object manipulation Understand how to manipulate data using arrays of structs Handle input errors and invalid values Design and create a wel-structure program using C++ basic programming constru Description: 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 substring and find the list of entries greater a given amount. Requirements: t allows the user to select a menu option to display all expenses, add new entry, search for a 1. The program must produce the same output as provided. The output should be formatted nicely as given. 2. The program must use array of structs 3. The program must not use global variables. In another words, it must use local variables and pass-by-value or pass-by-reference parameters 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 should use data file to save or read from. At the beginning of your program, it reads 4. 5. 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. You must write at least 2 functions. You need to submit both your program and data file "expensos.txt" 6. 7. Required error handling: The program MUST perform the following checks: ria 1. Check for invalid amount (negative or O number) 2. Description cannot be empty 3. Search is case-insensitive uiremen nd block c D:>TrackExpensesUsingArray.exe Welcome to my expense tracker.
