Question
Code the car class indicated below:
Car //name of class
- string model //private member variables
- int year
- double price
- string color
+ Car() //public class functions
+ Car(string newModel, int newYear, string newColor)
+ void setPrice(double newPrice)
+ void setColor(string newColor)
+ void setYear(int newYear)
+ void setModel(int newModel)
+ double getPrice() const
+ string getColor() const
+ int getYear() const
+ string getModel() const
+ bool operator>(const Car& obj) const (Cars are compared by price only)
+ bool operator<(const Car& obj) const
+ void display() const
Code the main function:
Write an program for NiftyGMC Dealer, which keeps track of their lot inventory. Your program is to allow the user to perform any of of the following until he/she wishes to exit: (program is to use either a vector or an Car array)
1 – add a Car to the Car inventory (user provides info on Car)
2 - print out all Cars
3 - accept a price from the user. Print out all Cars that are that price
4 - print out the cheapest Car on the lot
5 – ask the user to enter a color . Print out all vehcles that are that color
6 – ask the user for a year . print out all vehicles that were made that year
7 - EXIT
