1) For the usage of class "string" you have to use
#include <string>

and not
#include <string.h>

BTW: you can/should also use #include <iostream>

2) more conforming to ANSI C++ is to use additionally:

using namespace std;

    or using

"std::string" for all "string" occurrences.

On my c++ library it isn't necessary, but it should be ;-)


3) And to get rid of a warning you have to define an empty _virtual_ 
destructor for your student-class.

So the example of your student class is like this:

#ifndef STUDENT_H
#define STUDENT_H

#include <string>
#include <iostream>
// is it really necessary ?
// #include <stdlib.h>

using namespace std;

class student
{
protected:
   string   studName;
   string   studSSN;
public:
   virtual void identify();
   student(string sName,string sSSN):studName(sName),studSSN(sSSN) {};
   virtual ~student() {};
};
#endif
