Acknowledgement

I would like to express my sincere gratitude to my

computer science Teacher Mrs. Smera Girish for their

vital support guidance and encouragement without

which this project would not have come forth from my

side.

I would like to express my heartily gratitude to the lab

incharge , Mr. Vaibhav for his support during the making

of this project .

I would like to thank my parents and friends who have

helped me with their valuable suggestions and guidance

has been helpful in various phases of the completion of

the project.

TO CREATE A C++ PROGRAM FOR

PETROL PUMP MANAGEMENT SYSTEM

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
