Thread: Stack

I updated my coe and got it going guys but I have one final problem...my year is showing up wrong in the final out put!

Code:

#include <iostream>
#include <fstream>
#include <iomanip>
#include <functional>
#include <algorithm>
#include <string>
#include <cstdlib>
#include <sstream>
using namespace std;

class Car
{
private:
	class StackNode
	{
		friend class Car;
		string word;
		string wordTwo;
		string wordThree;
		int value;
		int valueTwo;
		StackNode *next;

		//Constructor
		StackNode(string word1, string word2, string word3, int value1, int value2, StackNode *next1 = NULL)
		{
			word = word1;
			wordTwo = word2;
			wordThree = word3;
			value = value1;
			value = value2;
			next = next1;
		}
	};
	StackNode *top;

	//Car Class information
    string make;  //make
    string model; // model
    string color;  // color
    int year;  // year
    int mileage;  // miles on car

public:
	Car() { top = NULL; }
		void push(string, string, string, int, int);
		void pop(string &, string &, string &, int &, int &);
		bool isEmpty();

        //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;}
