This document provides acknowledgements and thanks for those who helped with a hospital management database project. It thanks the teacher, friends, and seniors for their guidance, encouragement, information and experience during the project preparation. It includes the C++ code for the hospital management database program, which implements a queue to manage patients in different hospital departments like heart, lung, and plastic surgery. Users can add, remove, view patients and switch between departments using the program.

1. As usual a large number of people deserve my
thanks for the help they provided me for the
preparation of this project.
First of all I would like
to thank my teacher MR. N.G.B Singh Sir for his
support during the preparation of this project. I
am very thankful for his guidance.
I would also like
to thank my friends for the encouragement and
information about the topic they provided to me
during my efforts to prepare this topic.
At last but not the least I would like to thank
seniors for providing me their experience and being
with me during my work.

12. This program is mainly intended for the various
activities that are carried out at the Hospital. In this
project we included about how we can find out the
information about the various operations carried out
at a hospital.
The program is sub-divided into 4 departments listed
below:
Heart Clinic
Lung Clinic
Plastic Surgery
Exit
In this C++ program we can add, delete, recall and
modify the list of patients.
Being OOP concept available, we can add or remove
function anytime we need and even add classes and
derived classes for further improvement of the
program without recording.
