C++ Code Example - Student Roster

These are code samples from a final project used to complete a C++ course.  While the program functionality was simple, the instructions were designed to force many advanced methods to complete the objectives.

As this was (and may still a currently be) an assignment, I removed some key functionality and have not posted the complete source.

Student.h:

#ifndef STUDENT_H
#define STUDENT_H

#include "degree.h"
#include 
using namespace std;

public:
	//Accessors
	string GetStudentID();
	string GetStudentFirstName();
	string GetStudentLastName();
	string GetEmailAddress();
	int GetStudentAge();
	int GetDaysToComplete(int classNum);
	DegreeType GetDegreeType();

	
	//Mutators

	void SetStudentFirstName(string name);
	void SetStudentLastName(string name);

	void SetStudentAge(int ageNumber);
	void SetDaysToComplete(int days, int classNumber);
	void SetDegreeType(DegreeType type);
	//Constructor
	Student();
	//Destructor
