My previous project (in C++) had us writing a menu for a rental car service. Our menu included the following options:

1. Take in an input file of 5 cars and store it.

2. Print out all data for all cars to the terminal

3. Print out all data for all cars to an output file

4. Sort the car array by ascending price

5. Provide a list of cars along with their cost based on how many days they want the car

6. Provide cost based on the type of car and the number of days they want it

7. Exit program

Previous Project input file structure:

year, an int (year of production)

make, a C-string (char array of 10 maximum size)

model, a C-string (char array of 10 maximum size

price, a float (price per day)

available, a bool (1 = true; 0 = false; try to display true/falseSample Input File: (cars.txt)

2014 Toyota Tacoma 115.12 0

2015 Ford Fusion 90.89 1

2009 Dodge Neon 45.25 0

2015 Ford F150 112.83 1

2016 Subaru Outback 71.27 1

This is what my code ended up looking like

Description: This project will expand Project 2 by adding additional functionality, using pointers, and implementing abstract data types (ADTs) through classes. Pointers must be used for all array manipulation, including arrays with ADTs (structs, classes) e.g, rental cars, rental agencies. Pointers must be used in function prototypes and function parameter lists not square brackets. Make sure pointers (parameters list and function implementation). Square brackets are to be used only when (e.g.string copy, string compare, etc.) work with For this project, pointers can only be moved by conducting post/pre- in increment/decrement operations on them (ie., ++ or-), or by setting the pointer back to the base address using the array name. All pointers must be passed by value. Note Try to use the arrow operator (->) with Class Object pointers for member access, if you use such in your code.) The new functionality is as follows: You are given an updated data file (e.g. Agencies.txt) where there are 3 rental Car Agency locations, where each of the 3 locations (RentalAgency) has 5 cars (RentalCar). You will have similar menu options, but the functionality has been updated below. Note: using multiple helper functions to do smaller tasks will make this project significantly easier. You may want to create a function that will get a car from a location based on the location and car indices
