Question
This must be coded in c++. Thank you!
This is a sampe input file called Cars.txt
Description: For this project, you are to create a program that will assist users who want to rent a car. You are given a datafile with 5 different cars file (the file is a priori known to have exactly 5 entries, each following the same data layout), and you must read in all of the car data from the file and store it in an array of structs. You must also create a menu with the functionality defined below Although an example file is provided (Cars.txt), for grading purposes your project will be tested against a different test file that will not be provided to you beforehand. Our test file will be in the same format as the example file. The RentalCar struct will contain the following data members: 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/ false using the "std: :boolalpha" manipulator like: coutExplanation / Answer
