    Hey guys, I have been trying to do some stuff outside of my class to learn a bit more and I have come across something called a vector. And I read online that its similar to an array! But I am not sure how to do this. I have been able to find ways to convert and array of int's to a vector and how to convert an array of strings to a vector but nothing on how to convert an array of strings and ints to a vector. Here is the current code I have, you may have seen it before in my previous post just because I decided to use some code I had before that previously worked!!

    class
    Code:
    #include <iostream>
    #include <fstream>
    #include <iomanip>
    #include <functional>
    #include <algorithm>
    #include <string>
    #include <cstdlib>
    #include <sstream>
    #include <vector>  // this allows user to create a vector
    using namespace std;
    
    //Vehicle Class
    class Car
    {
    protected:
        string make;  //make
        string model; // model
        string color;  // color
        int    year;  // year
        int mileage;  // miles on car
    
    public:
            //Constructor that will set information for a new car
        void New_vehicle (string a, string b, string c, int d, int e) 
        {make = a; model = b; color = c; year = d; mileage = e;}
        
        Car(); //Default constructor
        Car(string, string, string, int, int);
        //mutator and accessor functions
        void setMake(string);
        void setModel(string);
        void setColor(string);
        void setYear(int);
        void setMileage(int);
    
        string getMake();

        string getColor();
        int getYear();
        int getMileage();
    
        //Check mileage to see if valid
        void valid_mileage(int);
        void car_details();

            cout << "WARNING! You have entered invalid mileage!\n";
        }

    I ran my code and everything looks perfect on it, but it keeps giving me errors!
