hashing help

[saiz66]

thanks a lot!

When I insert a Student S with age 4 and ID 5, and by the way I set the Student ID as the key.

Main Code:

int key =0, insertSuccess =0, retrieveSuccess;

Student S;
Student Answer;

Index<Student, int> I;

S.setAge(4);

S.setID(5);

insertSuccess = I.Insert(S);

cout << "Insert success = " << insertSuccess<< endl;

retrieveSuccess = I.Retrieve(5,Answer);

cout << "Retrieve success = " << retrieveSuccess<< endl;

cout << "Answer.ID = " << Answer.getID << endl;
cout << "Answer.Age = " << Answer.getAge << endl;

Student Class:

#ifndef STUDENT_HPP
#define STUDENT_HPP

class Student
{

private:

	// data members
	int itsID;
	int itsNumber;
	char itsName[20];
	int itsAge;
	char itsCollege;


public:
	// constructor
	Student ();

	// destructor
	~Student ();

	int Hash (int key);
	int Key () const;
	void setID (int id);
	int getID ();
	void setStudent(char name[]);
	int getStudent();

	void setNumber(int number);
	int getNumber();
	void setAge(int age);
	int getAge();
	void setCollege(char college);
	char getCollege();

	bool operator != (const Student &S) const
	{
		if (itsID != S.itsID)
			return true;
		else
			return false;
	}
};

#endif

#include "student.h"
#include <iostream.h>

Student::Student ()
{
}

// Student destructor
Student::~Student ()
{
}

int Student::Hash (int key)
{
	return key;
}

int Student::Key () const
{
	return itsID;
}


void Student::setID (int id)
{
	itsID = id;
}

int Student::getID ()
{
	return itsID;
}

void Student::setNumber(int number)
{
	itsNumber = number;
}

int Student::getNumber()
{
	return itsNumber;
}

void Student:: setAge(int age)
{
	itsAge = age;
}

int Student::getAge()
{
	return itsAge;
}

void Student::setCollege(char college)
{
	itsCollege = college;
}

char Student::getCollege()
{
	return itsCollege;
}

I think my insert works fine, but I could be wrong. I am trying to check if it inserted correctly and that is why I am trying to retrieve the Student class. When I try to retrieve it using a key that is not 5 it gives me 0 that it did not retrieve it, which should be correct because the key should be 5. Only when I put 5 in:

retrieveSuccess = I.Retrieve(5,Answer);

it gives me the answer 1 for retrieveSuccess that it retrieved that key since I set the ID to 5. Now the problem is that when I put the Student class into Answer, and I use Answer.getID and Answer.getAge it does not display the ID to 5 and Age to 4 but ID as 1 and Age as 1. Anybody can help me? Thanks in advance.
