Acknowledgement We would like to express our special thanks of gratitude to our lecturer Siti ‘Aisyah Binti Sa’adan who gave the golden opportunity to do this wonderful project as well as to our leader Ahmad Zharif Bin Mohd Nazri who distribute work for each of the members. Thank you again to our lecturer who also help us doing this project. We do a lot of research and all of us came to know about so many new things and we truly really thankful for them who help us. Then, we also would like to thank you to our classmates who helped us a lot in finalizing this project within the limited time framed and support us from behind.

Executive Summary Our project is to about implementation for a Patient program. A research has been made and we found that a lot of hospital did not use online registration. From this analysis we decided to design a program to help hospital business operation work efficiently. When the hospital use manual registration, it makes the employees at the hospital out of hand because of lot of patients. Besides that the hospital use manual registration that they must keep their patients record and the probability for documents to missing is high. Our objectives for this program is to do calculation to find summation for patient total bill, to find maximum highest total bill, and to search patient with heart attack disease. In this program, we use inheritance, polymorphism and input/output file. We using an abstract class for the patient class and having a sub class which is non-critical or critical patients. We also using input/output file that have name, id, illness, nationality, wards and how many days did the patients stay in the hospital. Next, it will display the patient's information. In the main, we using the polymorphism as the instanceof to critical and non-critical patient. We also get their information about either the patient is Malaysian or foreigner. The program will display the wards class either the patient take first class, second class or the third class. Moreover, after we know the wards class we will calculate the patient fee. The calculation are the wards class times with the number of the days did the patient stay in the hospital. The program will find the highest total bill. Then, it will display the information of the patient. The program also do the searching for the patients' information. After doing the searching, the program will display the information.
