Student Management System Project in C++

Dear Students, Today in C++ Programming Tutorial we will learn How to make a Student Management System Project in C++. Previously we shared Simple School Management C++ Project. It is a simple c++ project for beginners. To keep the project simple only basic functionalities has been added it is recommended for students first understand the project flow then add more functions like edit record (hint code also has given below) etc. Students are recommended to first add validation in this project which will not allow user to enter wrong option and then add more functions.

Students Management System Project in C++

Concepts used in C++ Project

This Project includes the concept of following topics:

struct
Filing
Loops
Arrays
If else
Switch statement
String class functions

Project has for major functions in menu

Insert record
Show all record
Search record
Exit program

How it works

Each functionality has a function call in switch statement on the user choice control transfers to a function. Every function opens a file name "database" and insert, show and search data from it. File will be created where c++ file is placed in secondary storage.

School Management System Project Output

Source code has been tested on Microsoft Visual C++ compiler. If you are running on a different compiler like codeBlocks. Some changes may required like add using namespace std; , remover .h from iostream etc.

Reference edit functionality c++ source code
