Simple College Management System using C++ (With Source Code)

Hello, coders. Welcome to the codewithrandom blog. In this article, we will learn how to create a Simple College Management System using C++ (With Source Code).

What is a College Management System?

The Simple College Management System is a console based application which allows the user to manage a collection of student records in a college. This system accurately collects the college students information to add it to the records securely for further use by the administration of the college. It stores the following information of a student – Name, registration number, roll number, branch in college and etc. The system contains various functions to perform operations such as add new records, display records, remove/delete a student record, edit a record and search a student record.

In general, College Management System is a vital tool that assists colleges and universities in streamlining their operations, increasing efficiency, and improving student experiences. It provides a centralized platform for handling numerous administrative and academic responsibilities and handling student records in a convenient manner making it easier for institutions to provide student data to the administration and faculty to use it for further requirements.

Simple Clinic Management System using C++ (With Source Code)

The program for this project uses the concept of vectors to store the student records.

Overview of the UI:

• Enter <1> to Add new student
• Enter <2> to Display all student
• Enter <3> to Remove student
• Enter <4> to Edit student
• Enter <5> to Search student
• Enter <0> to Exit

The user will choose an option to proceed further to perform a function in the College Management System.

You can directly use this code by copying it in your IDE to understand the working and then can create it by understanding the project.

Now let us understand the code:-

• We will start by writing the header of the code with the required libraries – iostream, vector, stdio.h, cstring, fstream, and algorithm.
• Now we will define a class called student which will have three member variables -req (registration number), name (name of the student) and branch(branch of the student)and the member functions- input() and display() to input and display the student details respectively. The == operatoroverloading function is used to compare two student objects based on their registration numbers.
• We will create a vector v of student objects to store the student records.
• For the functionality of the program, we will declare the following functions:-
• The get_file() function uses an if-else statement with a while loop to read the student records from a file named “College.txt” and then store them in the vector v.
• The bubblesort() function uses a nested for loop and an if statement to sort the student records in ascending order of their registration numbers using the bubble sort algorithm.
• The insert_new() function uses a while loop with an if – else control statement to allow the user to add a new student record to the vector v.
• The write_file() function uses a for loop to save the student records in the vector v to the file named “College.txt”.
• The search_reg(long int reg,int &i) function uses a for loop and an if control statement to search the vector v for a student record based on the registration number and returns the index of the record if found.
• The search_name(char name[],vector<int> &vi) function uses a for loop and an if control statement to search the vector v for student records based on the name and returns a vector of indices of the matching records.
• The search_branch(char branch[],vector<int> &vj) function uses a for loop and an if control statement to search the vector v for student records  by the branch and then return a vector of indices of the matching records.
• The search_and_show() function uses a switch case to select between the options to search for a record either by registration number, name or branch of a student. It then displays the matching records.
• The show() function displays uses a for loop to show all the student records in the vector v.
• The delete_data() function uses an if control statement and allow the user to delete a student record from the vector v.
• The edit_data() function uses an if control statement and will allow the user to edit a student record in the vector v.
• The main() function will display a list of options to the user to choose the operation they want to perform. It uses switch case statements to select between the options for the corresponding function calls.
• This sums up our project of College Management System using C++.
