The document outlines a computer science project by Rushil Aggarwal, a Class XII student, focusing on a C++ program for a petrol pump management system. It covers various functionalities including adding, displaying, and finding records, as well as includes relevant coding and bibliographic references. The project has been developed under the guidance of Mrs. Smera Girish, with acknowledgements to support received from teachers, lab incharge, and peers.

5. AIM
TO CREATE A C++ PROGRAM FOR
PETROL PUMP MANAGEMENT SYSTEM

6. INTRODUCTION
This program is mainly intended for the various
activities that are carried out at the petrol pump and
service station. In this project we included about how
we can find out the information about the various
operations carried out at a petrol pump.
The program is sub-divided into 4 domains listed below
 Add new record
 Display all record
 Find a record
 Exit
