write a c++ program all in one file please. 

In this assignment, you are going to build a program that can help rental car companies to manage their rental fleet. Requirement: - build vector class as container. - build Car class/structure to represent car objects. - An vector object is to hold Car objects. Car class should have following fields: - id (int) - make (string) - model (string) - color (string)

 make up 15 cars and save them into a file: cars.data load these cars' info from the file, initialize 15 Car objects, place them into the vector if new cars are added by user, they should be appended to the cars.data file when exiting the program design a menu based user interface that allows following operations: search by id search by make search by model search by color add a new car (new car id cannot be same as existing ones) delete an existing car by id list all cars exit the program 

This is all the information I have please just do the best that can be done.
