INTRODUCTION

What’s a Hostel Management System (HMS)?

“HOSTEL MANAGEMENT SYSTEM” is software developed for managing various activities in the hostel. For the past few years the numbers of the educational institutions are increasing rapidly. This particular project deals with the problems on managing a hostel and avoids the problems which occur when carried manually.

This mini project Hostel management system project is developed using C Programming Language and different variables, strings have been used for the development of it.

We can save , view, edit , delete all details of student in hostel such as name , contact no., room no., address etc.

We have used file handling for saving all the details of student and data structure concepts are used for editing and deleting the stored data of student in hostel.

Objectives:

About Hostel Management System:

File handling, data structure, functions, and pointers are the main things which make up this simple C mini project. The key features of hostel management system are listed below:

• Add new student’s data: Enter information such as hostel _id, name, age, fathers name, phone number, fathers phone no., address, email and hostel group (BH-1,BH-2,BH-3,GH-1).

• Update information of existing students account: Update details of particular student account.

• Check details of existing account: based on hostel _ id and name.

• View all students of particular hostel group: using choices such as BH-1,BH-2,BH-3,GH-1.

•Delete existing account: by entering hostel _ id.

•View all total students in hostel.

•Exit.

Algorithm:

Step 1: Start.

Step 2: Login.

Step 3: Select the choice.

Step 4:

Case 1: Add new student’s data.

Case 2: Update information of existing students account.

Case 3: Check details of existing account.

Case 4: View all students of particular hostel group.

Case 5: Delete existing account.

Case 6: View all total students list in hostel.

Step 5: Exit.
