Each student entry in the database has the following fields: Name, Student ID, Address, and Telephone Number.

***INSTRUCTIONS ON HOW TO COMPILE AND RUN THE PROGRAMS***

1. Run terminal and navigate to the root folder of this file.
2. Type "make". This would compile the code.
3. Type "./{FILENAME}" to run each program. e.g ./load or ./print


**NOTE**

1.The student data is stored in the file called person.dat. this was created using the code found in data_writer.c

2. Then you run print, maximize terminal to get the optimal view
