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!!

#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
{

	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 getModel();
    string getColor();
    int getYear();
    int getMileage();

	//Check mileage to see if valid
    void valid_mileage(int);
    void car_details();
    string string_car_details();
};

//Sets to default values
Car::Car() {
	make = " ";
    model = " ";
    color = " ";
    year = 0;
    mileage = 0;
}
	// My Vehicle set up(Make, model, color, year, type,bedsize, bike, mileage)
Car::Car(string make, string model, string color, int year, int mileage) {
	Car::make =  make;
	Car::model = model;
	Car::color = color;
	Car::year = year;
    valid_mileage(mileage);
}

void Car::setMake(string make) {
    Car::make = make;
}

void Car::setModel(string model) {
    Car::model = model;
}

void Car::setColor(string color) {
    Car::color = color;
}

void Car::setYear(int year) {
    Car::year = year;
}

void Car::setMileage(int mileage) {
    valid_mileage(mileage);
}


string Car::getMake() {
    return make;
}
string Car::getModel() {
    return model;
}
string Car::getColor() {
    return color;
}
int Car::getYear() {
    return year;
}
int Car::getMileage() {
    return mileage;
}


void Car::valid_mileage(int mileage) {
    if (mileage>=0)
        Car::mileage=mileage;
    else {
        Car::mileage=0;
        cout << "WARNING! You have entered invalid mileage!\n";
	}
    }

	void Car::car_details() {
	    cout << "The current car is a " << year << ' ' << color << ' '
			<< make << ' ' << model << " with " << mileage << " miles.\n\n";
	}



	string Car::string_car_details() {

	    return buf.str();

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

Ok guys my code works but I got a question. How would I make a change to a year or something in this vector and print it for the user??

How would I make a change to a year or something in this vector

See vector::operator[]. At the bottom of that page are links to other vector accessors. Also you might use iterators, also explained there.

>> and print it for the user??
You are doing it already ..

std::cout << CarVector[i].getMake() << std::endl;
