I Introduction.

The Student Management System is a software applicationdesigned to efficiently manage and organize student information.This system offers a convenient and structured approach to storingand retrieving data related to students, including their personaldetails, academic records, and contact information

The primary goal of the Student Management System is tostreamline the process of managing student information, ensuringeasy accessibility, accurate data storage, and efficient datamanipulation By employing a stack data structure in itsimplementation, the system leverages the benefits of stackoperations such as push, pop, and peek, which allow for efficientinsertion, deletion, and retrieval of student records

Managing student information effectively is of paramountimportance in educational institutions, as it enables administrators,teachers, and support staff to maintain accurate and up-to-daterecords, facilitate communication with students and parents, andgenerate various reports and analyses for academic andadministrative purposes

The use of a stack data structure in the implementation of theStudent Management System offers several advantages The stack'slast-in-first-out (LIFO) property ensures that the most recentlyadded student record is easily accessible and modifiable.Additionally, the stack's efficient push-and-pop operations enablethe system to handle frequent updates and changes in studentinformation seamlessly

This report will delve into the design, implementation, andresults of the Student Management System We will explore thestructure and functionality of the Student and Stack classes,analyze the flow of control in the program, and discuss the benefitsand effectiveness of utilizing a stack data structure in the context ofstudent management

II Design.

The design of the Student Management System encompassesthe structure and functionality of the software application Thissection will explore the key design aspects, including the classstructure, relationships, and the rationale behind utilizing a stackdata structure

The system is implemented using the C++ programminglanguage and consists of two main classes: the Student and Stackclasses The Student class represents an individual student andstores information such as the student's ID, name, address, phonenumber, email, date of birth, and GPA This class also providesgetter and setter functions to access and modify the student'sattributes

The Stack class represents a stack data structure that holdsStudent objects It is implemented using a linked list, where eachnode contains a Student object and a pointer to the next node TheStack class provides various functions to manipulate the stack,including push (to add a student to the top of the stack), pop (to

remove and return the top student), peek (to access the top studentwithout removal), isEmpty (to check if the stack is empty), getSize(to retrieve the size of the stack), display (to print the stackcontents), remove (to remove a student by ID), find (to search for astudent based on a given condition), and sort (to sort the stackusing a comparison function).

The Student Management System employs a stack datastructure to store and manage student information The decision touse a stack is motivated by its LIFO (last-in-first-out) behavior,which aligns well with the requirements of managing studentrecords New students are added to the top of the stack, allowingeasy access and modification of the most recent student records

This design choice ensures that the latest student information isreadily available and simplifies tasks such as updating, removing,and searching for student records.

The Student Management System follows a modular design,dividing the functionality into separate classes This promotesencapsulation, code reusability, and maintainability The use ofclasses allows for better organization and abstraction of thesystem's components, making the code easier to understand andmodify

Overall, the design of the Student Management Systemfocuses on providing an efficient and organized approach tomanaging student information By utilizing the stack data structureand employing a modular class-based design, the system aims tostreamline the process of storing, retrieving, updating, andsearching for student records.

With the design of the Student Management Systemestablished, we can now move on to the implementation details

The following section will delve into the coding aspects and provideinsights into how the system was realized in practice.

1 Student Class Implementation.

The Student class was implemented to represent an individualstudent and store relevant information The class contains privatedata members for the student's ID, name, address, phone number,email, date of birth, and GPA It also includes getter and setterfunctions to access and modify these attributes

Student Class Header File

// A class to store student information

string name ; // Student name

string address ; // Student address

string phone ; // Student phone number

string email ; // Student email

string dob ; // Student date of birth

double GPA ; // Student GPA

// Public member functions

doublegetGPA ();

// Setter functions

void setName ( string );

void setAddress ( string );

void setPhone ( string );

void setEmail ( string );

void setDob ( string );

void setGPA (double);

or provided attribute values The getter functions retrieve thevalues of the student's attributes, while the setter functions modifythem The display function prints the student's information to theconsole

2 Stack Class Implementation.

The Stack class was implemented to represent a stack datastructure and provide the necessary operations for managingstudent records It is implemented using a linked list, where eachnode holds a Student object and a pointer to the next node

The Stack class provides various functions to manipulate thestack of student records The push function adds a new student tothe top of the stack, while the pop function removes and returns thestudent from the top of the stack The peek function allowsaccessing the top student without removing it The isEmptyfunction checks if the stack is empty, and the getSize functionreturns the current size of the stack

Stack Class Header File

Student * data ; // The student data

Node * next ; // The pointer to the next node

friend class Stack ; // Class Stack can access the private members of class Node

public:

// Parameterized constructor

Node ( Student* data) {

this-> data =data;

this-> next = nullptr ;

}

};

private:

// Private data members

Node * top ; // The pointer to the top node of the stack

int size ; // The size of the stack

// Public member functions

// Push function to add a student to the top of the stack

void push ( Student* data);

// Pop function to remove and return the student from the top of the stack

Student* pop ();

// Peek function to return the student from the top of the stack without removing it

Student* peek ();

// IsEmpty function to check if the stack is empty

bool isEmpty () const;

// Size function to return the size of the stack

int getSize ()const;

// Display function to display the stack

void display ();

// Remove function to remove a student by ID

Student* remove (int);

Student* find (function bool(< Student * ) > condition);

// Sort function to sort the stack using a std::function object

3 Main Program Implementation:

The main program logic is implemented in the `main`function It presents a menu-driven interface for interacting withthe Student Management System Users can choose various optionssuch as adding a student, updating student information, removing astudent, displaying the stack, searching for students by ID, name,

or GPA, and sorting the stack

The implementation utilizes the functionalities provided by theStudent and Stack classes to perform these operations efficiently.Users are prompted to enter the required information for eachoperation, and appropriate feedback is displayed to indicate thesuccess or failure of the requested action
