Student Data Management in C++

Databases are being used in every aspect of our lives right now. Trillions of bytes of data are being stored in servers around the world. SQL is one of the most basic methods to use such a database. But have you ever thought about using C++ to maintain such a database. In this post, we will talk about implementing different views on a text file according to the type of user and edit accordingly.

The data stored using this code are: 
1) Registration number 
2) Name 
3) Marks in CSE1001 
4) Marks in CSE1002 
5) Proctor ID

Following code is a simple implementation of Student Management Project written in C++

Do note that I have set the pointer position according to the length of the data I am entering in the text file. Some of the things which I had assumed are the registration number is always 9 characters long, subject code is either CSE1001/CSE1002, proctor ID is 4 characters long, marks is just 2 characters long. You would need to change the code accordingly if you want to enter some other type of data.
