Help with program using classes

Please help. The code below will compile and run using the Dev C compiler, but not the Visual C++ 2005 express edition. I need it to run in the express editions. any suggestions?

Code:

#include "stdafx.h"
#include <iostream>
#include <string>
#include <stdlib.h>
#include <algorithm>

using namespace std;
using std::cout;
using std::cin;

class student

{

             student();

             void student1Input(string fName, string lName, int id);
             void student2Input(string fName, string lName, int id);

             int student1maxMin();
             int student2maxMin();

          private:

                         int id, max, min;

             double sum, avg;
